My Girlfriend's Friend

With medical school on the horizon and his future carefully mapped out, high school guy Takeru Hidaka has a clear plan: study hard, get into medical school, and keep his life on track. He's even got a girlfriend now, Kaori Koga, and things between them look pretty solid from the outside. Then Kaori's best friend, Tomoko Yoshioka, enters the picture — and she is not interested in keeping her distance. What starts as an uncomfortable situation slowly pulls Takeru into something he knows is wrong but can't quite walk away from. Now he's maintaining two versions of himself, lying to someone who trusts him, and trying to figure out how he got here in the first place. The series doesn't frame any of this as romantic or exciting — it sits with the discomfort, which is actually what makes it interesting. If you've seen Kuzu no Honkai or White Album 2, you know this territory: messy people making choices that feel disturbingly real, where nobody is cleanly the villain. It draws from a web manga source, so the storytelling leans into character interiority and slow-burn tension rather than dramatic plot twists. It's not an easy watch if you're hoping for a wholesome romance, but if you want something that treats its characters as genuinely complicated and doesn't let anyone off the hook too easily, this one might be worth your time. Just go in knowing it's more emotional wreckage than feel-good story.
