So like Hoshi is just a fuck boy isn't he? Or at least the author portrayed him like this because: 1)He was completely smitten with Senko and even confessed to her a couple of times. Thankfully Senko didn't even skip a beat and basically rejected them.
2)Then despite Senko clearly being in love with Takamura, he continued lewding her and basically trying to win her attention only being unsuccessful due to Takamura's active attempts to prevent him from getting close.
3) Then the moment he met Eruko he becomes completely smitten with her instead and now confesses. (clearly the fucker is lucky cause Eruko is like the hottest piece of ass in this manga and she's lewd
I dunno, I am just not liking his character much. Only reading this for Eruko
