Bo Nui (Hwang Jung Eum) goes to her intro to technology class that she teaches and they’re going to learn how to use video chat and messenger apps.
Hee Ae (Na Yong Hee) and Mool Po (Gi Ja Bong) set out Mool Po’s birthday meal. He asks if Soo Ho (Ryu Jun Yeol) is coming because he’s told her to stop. She tells him that she put out the plates just in case he came. When she tries to get Mool Po to put the hat on Soo Ho tells him that he should. They sit for the meal and Hee Ae tells Soo Ho that she’s stopped seeing the shaman because she couldn’t believe that she told Bo Nui that she was the racoon.
Seol Hee (Lee Chung Ah) was talking with a prospective client trying to convince the mother into letting her manage her kid when Gary (Lee Soo Hyuk) shows up. He happened to be shooting an interview at the same place she was. She tells him that she’s so proud of him and asks if he’s seeing anyone because he’s always in the middle of a call. They part ways and she tells him to cheer up. (That suit thought *shivers*)
Dae Tae (Kim Sang Ho) hands a paper file to Soo Ho and is informed this is useless. He reminds him that he offered to pay for cram school. Young Il (Jung In Gi) says that he’s been teaching him. Soo Ho wonders why he wrote the file by hand then. Ryang Ha (Jung Song Hoon) comes in to announce that IF has been released.
Ryang Ha is driving Soo Ho and asking him about his plans for the new game. He goes off about his stocks and Soo Ho mentions that there are no stocks. Soo Ho nicks down every argument that he has and Ryang Ha asks if he’s reading his heart.
Soo Ho goes to visit Zeze for their launch and everyone is happy to see him. They ask him if he’s coming back and he tells them that he’s Jackpot and he will work hard to compete against Zeze. They all wish him luck.
Bo Nui comes home to find a note that Bo Ra (Kim Ji Min) has gone to Seoul.
Soo Ho happens upon Bo Ra, who’s stuck on a corner. He’s is shocked at first and then helps her. He asks if she came alone, looking around for Bo Nui. She tells him that she’s not a child, and he calls her smart. She asks him if he knows where Zeze factory is, and he asks why she just says she has someone to meet there. He offers to take her there. She wonders briefly why his voice sounds familiar he simply brushes it off.
Dal Nim (Lee Cho Hee) calls Bo Nui and tells her the Bo Ra is at Zeze. Dal Nim comes in and tells her she should have called. She tells her that she didn’t want to let her sister know that she was coming. She tells her she’s on a mission to find Soo Ho (*giggles*). Dal Nim asks if Bo Nui had told her anything and she tells her that it’s the exact opposite. BoNui tells her everything but nothing about her time at Zeze or Soo Ho.
Gary comes and hands gifts to every one of the Zeze development team and thanks them for making a life much cooler than his own. They’re all talking about his game when he gets a call from Bo Ra and finds out that she’s at Zeze.
Gary enters the room and Dal Nim tells him she has to meet with the reporters but Bo Nui should be there soon. He agrees to sit with her while she plays. She starts raving about the games and is shocked that her sister designed it. Gun Wook tells her that she made it with her in mind. He wasn’t going to be the model but after he heard that he had to be. She mentions that since they met he could give her some autographs because the neighbour’s kids don’t believe that she’s close to him. She tells him she only needs 10. While he’s signing she tells him that she thinks he’s gotten better looking and you can totally tell she’s crushing on him.
Soo Ho waits out front of Zeze to catch a glimpse of Bo Nui. He hears her get out of the cab and answer the phone. For a moment time seemed to slow and he walks away happy.
Bo Nui storms and yells at Bo Ra. Bo Ra asks Gary if he called her and her retorts that he though she told her she was coming. Bo Ra apologises and asks about the game. Bo Nui confirms all the information that Gary gave and when Bo Ra tells her good job. Bo Nui can’t stay mad.
Bo Nui and Gun Wook go to have coffee on the roof. She complains about Bo Ra and how she calls him all the time. He assures her that it’s not hard to pick up the phone. They talk briefly about his father and make plans to eat together. Gun Wook suggests that she should move back to Seoul because Bo Ra seems to feel trapped and it would make her job easier. She tells her that she’ll see, no one knows the future.
Bo Nui sits down with Dal Nim and Dal Nim complains that she thought she left. Bo Ra tells her that she needs to be the one with the first invite. Dal Nim hands her the invite to her and Ryang Ha’s wedding. Bo Nui looks uncertain but she promises that she will go to the wedding regardless of her fear of bumping into Soo Ho.
Soo Ho arrives back at his office and pulls out a book from his bag. From the book, he extracts the picture of himself, Bo Ra and Bo Nui together. He looks at it fondly before placing it back into the book.
Bo Ra hands Bo Nui an envelope. Inside is an application for a Game Concept Contest. She tries to get her to register because she thinks she can win with what she’s been working on. When Bo Nui walks away Bo Ra calls Dal Nim and tells her that she gave her the application but she’s not sure that she’ll go for it.
After Dal Nim hangs up the phone Ryang Ha shows up acting all cute. She asks if he’s given the invitation to Soo Ho but he admits that he forgot. Dal Nim is planning for the couple to meet again at their marriage and fall in love. He admits that he doesn’t like being the side characters, but Dal Nim tells him that she wants everyone to be happy and he agrees. (Seriously watch this scene. You’ll piss yourself laughing.)
Gary meets with Amy and she teases him about habits being hard to break. Though she’s no longer his agent they still jump at the chance to meet. He asks about her recruits and she tells him there isn’t one. She assures him that hen there is it’ll be a huge headline and he tells her to do it with his name. She thought she misheard, and he tells her that he left IM and she could recruit him. She asks why he left, and he admits that it’s because she isn’t there and it isn’t fun working there when there is no one to tease. She agrees and offers monthly instalments of hs signing fee and he agrees.
Bo Nui is walking home when she gets a call telling her that she has passed the first stage of the contest. She tells Bo Ra who is super happy for her sister. She tells her that she’s certain that she’ll win. She asks about the game, but Bo Nui tells her that she still has to pick an ending and once she has then she’ll tell her about it.
Soo Ho asks what the investors not like about the game, Young Il (Jung In Gi) tells him that they don’ like the cave or the character. He tells them that they’ll scrap the game, and when Dae Tae protests, Soo Ho explains that no matter what they change they’re not going to like it. Young Il agrees with him, but tacks on that they still need money.
Soo Ho meets with Ryang Ha and tells him to forget the investor because he’s wasting their time. Ryang Ha tries to convince him otherwise but Soo Ho doesn’t agree with him. No matter what idea Ryang Ha offers, Soo Ho shoots them down. Ryang Ha is about to leave when he remembers the wedding invitation. He tells Soo Ho that he has to come before leaving.
We get a lovely collage of Soo Ho and Bo Nui working on their respective games. and More of Soo Ho’s glasses.
Once Bo Nui is done she Bo Ra calls to her. Bo Nui tells her to sleep and holds her hand. Bo Ra tells her that she remembers waiting for her to hold her hand and talk with her. She remembers fighting so hard after hearing her voice when she came with the man. She asks if she remembers and she tells her that she doesn’t remember all of it, but she remembers his voice and what he said. She wants to meet him and thank him for bringing her sister back to her.
When Bo Nui gets to the presentation hall, Dal Nim is there waiting for her. She inquires as to how she knew that she was coming and Dal Nim admits that Bo Ra called her to let her know. She jokes about Bo Nui not needing a rabbit suit anymore. Bo Nui admits that she’s nervous and Dal Nim offers her a hug. She tells her that she has to win 1st prize and get her a wedding present. They make that the deal before Dal Nim runs back to the office.
Ryang Ha is at the office, freaking out about Soo Ho going missing. Dae Tae suggests just to print out the plans and have the meeting himself. Everyone thinks it’s a good idea, but when they check there are no files.
Soo Ho arrives at the competition and watches Bo Nui’s presentation. When Bo Nui sits down it’s time for Soo Ho to present and she’s shocked to see him. We have her an overlap of the 2 presentations, that start off very similar. Bo Nui’s game is about a girl who has the worst luck, who is given a knife to hurt people she loves. The game starts with a letter that the girl received when she loses everything. We get to see the letter that Soo Ho wrote for her when they parted ways. He tells her that her knife was a light that helps him no matter what. He ends off with him loving her. Their games mirror each other, her game about the girl trying to respond to a boy calling her his light and his game about a boy searching for his light.
After the presentations, the two of them meet up. Their voice over says everything. She apologises for taking so long and she will only think about her happiness and he chastises her for taking so long to get to the correct answer. They pull each other into a hug.
Ryang ha comes to visit Dal Nim and no one says hi because he comes so often. He starts serenading Dal Nim much to the irritation of their coworkers.
Dal Nim is waiting at the Daebak office when Soo Ho comes back. He asks where the other 2 went and she tells him she’s to call them when he gets back. He talks about the how releasing Miracle and Will like twins. He pauses and Bo Nui understands it’ll be hard and they should release Miracle first, he then tells her they think they’re geniuses and invested 100%. Bo Nui is so happy because Bo Ra was singing about it. Soo Ho remembers that Bo Ra is waiting.
They pull up in front of their old home and Bo Ra asks to stay outside for a second, finally feeling home. They get up to her rooms and Soo Ho opens the door. He tells them to go in and he’ll be on the roof. Everything is the exact same as when they left and Bo Nui isn’t quite sure how. Bo Ra reminisces about the drawing that hanging on the wall. Bo Nui repeats what she said when she put it up. “We’re not 2 people but 4 because mum and dad are watching over us.” Bo Ra mentions that they’re 5 now.
Bo Nui goes to the roof and gives Soo Ho a hug from behind. She thanks him and promises to be good from then on. She tells him that it’s not enough and he agrees. She tells him that she’s grateful and heads in to eat.
They sit down to eat and Bo Ra asks how someone could be so crafty. He asks what he did and she knows that he set up everything without her sister knowing, she tells him that he even pretended not to know her. He accuses of her not recognising him, and when she tells him that her memory fails, he tells her to memorize the 10 multiplication table with him. They have a little squirmish about her not liking math.
When Bo Nui finally settles down the door rings and it’s Amy and Gary. They came to congratulate the move and when Bo Nui asks if he called them he admits be prefer when it’s just them. Bo Ra calls from inside and Gary walks in. Next Ryang Ha and Dal Nim show up. Though Soo Ho tries to block them at the door they let themselves in. They had a very energetic evening together.
Soo Ho calls from the car and they get ready for a picnic. Suddenly it starts to pour and Soo Ho declares that they picnic is cancelled. Bo Nui asks what’s a little rain. They end up playing in the rain. Their voice over says that though her fortune might be a little rough at times they decided to live in the present.
The finally truth or dare is the epilogue. The Shaman vacates his premises. Bo Nui and Soo Ho are walking and it had stopped raining. He’s happy they came and when she asks if she’ll always be in it with her together, he reminds her that he likes yes. She proposes to him and tells him no matter how she looks at it, it has to be him. He says yes and starts running around before finally stopping. We get 1 final kiss.
