Discovered this story a bit late. I kinda like that none of the characters are perfect and how different each of them are. I hope Hananoi will eventually become more confident aside from opening up. I can see that they are doing their best to have a healthy relationship with each other!
This is just a guess. But I think Claude's head does not hurt when Jenette is around simply because Athy is around as well? Considering the flashback of the actual after ending of Lovely Princess :(
