Title: Kiss Me like You Did that Day
Miho still remembers Hiroya. Miho is a working adult, a writer who works from home, and he's already gone through a divorce. Yet, Miho can still remember, as clearly as if it were yesterday, the day his only friend from high school, Hiroya, kissed him. Unfortunately, after their kiss, Hiroya's immediate response was to apologize. As a result, Miho assumed that Hiroya didn't mean it and regretted it. Heartbroken, Miho ran away, deleted Hiroya's number, and never looked back. Yet, Miho constantly thinks of Hiroya and what life might have been like if they had never kissed.
Because of his curiosity and despite his introverted personality, when Miho receives a notice about a high school reunion, he goes, hoping Hiroya will show up. When he arrives, his former classmates are surprised, as Miho was known in high school for being a loner and having no friends other than Hiroya, who hasn't shown up. Miho is just about to give up when Hiroya shows up. The two instantly recognize each other, even after all of this time, but before they can catch up, Hiroya is swarmed. This is just one more reminder to Miho why they could never work out. Hiroya is a social butterfly, while Miho could never even make a friend that wasn't Hiroya. Then, he hears that Hiroya is going through a divorce. Feeling like there was no point in coming, Miho leaves, intending to return to his life without Hiroya.
But Hiroya chases after him. He begs to have dinner, which Miho concedes to. Over food, the two share stories about their lives and apologize for the pain they caused each other. Throughout their conversation, Hiroya mentions needing to move out of his ex-wife's home. When Miho mentions having an empty room because of his divorce, Hiroya asks Miho if he can move in. Though Miho knows this might be a bad idea, the prospect of rebuilding his relationship with Hiroya is too tempting, so he agrees to let Hiroya move in. What will living in close quarters mean for these two? Will they be able to get along, or will their relationship fall into shambles like before?
