The story does get some intrigue from its abrupt narrative shifts and unexpected endings, but being this short, I think it ultimately feels too unfocused.
To illustrate the point further: the opening is functional slife-of-life stuff on paper, but it might not set the mood well enough (many of the details feel a bit generic or repetitive, especially how often smells are described) to justify its inclusion. It feels like the game only really begins when we get to the gym and hang out with Ken. That part, meanwhile, sets up some compelling drama – such as the troubles the characters would have visiting each other after the protagonist moves – but doesn't really follow up on any of it.
Instead, we get a choice leading to three different endings. The logic behind them doesn't feel transparent; I get why hanging out with Ken is the good ending, but it doesn't feel like his invitation actually has anything to do with whether the protagonist decides to get coffee or not. Clarity of cause and effect would probably have helped this part land, and combined with the two bad (?) endings being weird in general, I fear I had a difficult time getting anything from the story.
