If we're talking about the romance in the story I think it'll go like this: Blue haired missy becomes attracted to Ah Dai, though since she's an extreme tsun-tsun there won't be any devolopement in that area. Then either she discovers he has a fiancé or/and the fiancé shows herself, then stuff will get started. I think the fiancé will either be a horrible coward, snob or nice and caring. Well I will only ship him with the missy if she has a character growth. End of my hipothesis
You all are hating on her because you think that she doesn't try to understand Riku, well, you're right. But at the same time I think it would be kinda lame for her to already understand him? I'm reading this manga cuz' it fucking awesome and because I hope that their will be interesting character developments, the one's I'm the most interested in is the girl's and Riku's. For now I don't ship them, but in the future....ლ(´ڡ`ლ)
she's known him for years, she should have SOME type of understanding about how he thinks. something. anything. she has none. she knows what everybody else knows about him. he lives to box (and that he killed someone but that's besides the point). she doesn't even want to know WHY. really? THAT'S super lame. so fuck her
Jun knows the feeling of restraint...
