Honestly I didn't like her at the beginning myself and I felt she was very shitty to mc however, it takes a lot of growth in a person to truly apologize about something they done its really hard to do oddly. The character development in her compared to the other girls is huge and honestly cause she and mc have long relationship since childhood she definitely end game for him since he only wrote those stories for her to begin with. It's not what I hoped but I can't complain, I like her a more then other similar characters from a different series who come off more pretentious then sincere.
Michirou is a terribly flawed person... and will probably be the end game love interest which is crazy im sorry
