I kinda wanted an ending that Yuki would let his past go, and be able to overcome this love and find another person after dealing with his issues. The couple didn't have a good chemistry. I'm saying this being a person who fucking loves friends to lovers, but their development wasn't good at all the ending felt... forced.
I do also think that if masaki had gotten well build up characterization I'd be rooting for him, but all the story, everything was a messy. But at least even being a side character he seemed more interesting lol I'd totally read a story about him.
