I've said it before, and I'll say it again that romance, and maybe character relationship included, is the weakest link in this anime. I do not understand how some couple are made, they suddenl become one off screen, and again let me remind you that Minori is a 14 YEAR OLD MIDDLE SCHOOLER, while Shiro is a 23 YEAR OLD MASTER STUDENT. It always feels icky how the writer kept pushing them together and to the audience. Then again, the writer knows everything and maybe know that Shiro likes someone like Minori, small and can't consent. I'm being sarcastic, by the way.
