She's too selfless and understanding about her boyfriend? Uhhh do I need to bring back how she handled Long's confession and clinginess and then Kouhai's advances up to this point? She didn't understand nor care about his feelings at all!
Also, didn't we have a very similar situation in chapter 13?? I guess the only way the author can try to make Soushi seem childish and have reasons to dislike him is to do something like what Megumi already did.
