(pm ch.7 spoiler alert)
you are indeed right about things seeming awkward between yacchan and kashima and that's mainly due to yacchan having a huge inferiority complex towards kashima. and rather than saying he is trying to change to become a better person it's more like he is trying to act like kashima to be liked (since kashima's outgoing happy nature makes him pretty popular)
Can you link chapter 7?
Ehhhh...That Makes Him Kinda Sad In A Way Doesn't It? Their Development Should Be interesting
I'm starting to wonder if something happened to Yuri that made him decide to act like he's lost his mind when he hasn't or if he does it cause he feels like he couldn't find someone to truly love him and not just want his goodies...Yacchan Yacchan it seems like he used to be a troublemaker but is trying to change..but sometimes him and Yuu act so awkward w/ each other it's like hmmmm...and I want Itome to say to say that he only wants Akemi to be w/ him =/ and Akemi knows that's what he wants -__-
