Seriously, what's up with Minori? Two chapters ago, she's explaining her feelings to Youtarou, saying she wants him to think of her as "the most important person in his heart", here she's gets flustered when Tusbasa calls her by her name and gets angry at Youtarou when Tsubasa does the same to him.
This flip-flopping with her character has been going on for quite a while. It's like the author took Minami and Miharu from Baka to Test and combined them to make Minori. Even the other characters are confused with how Minori is acting, almost like the author is making light of his/her inconsistent character writing.
Pick a lane and stick with it author; does Minori want to be with Youtarou or Tsubasa?
