Interesting.... very interesting. I wish there were more chapters though. I feel like Shuzo Oshimi could have gone somewhere with this storyline or at least elevate it like he did with The Flowers of Evil. I mean there must have been a cliffhanger for a reason right?
My initial annoyance has turned into something of admiration. Maybe it's the succinctness. I now think this is a good entry in the mangaka's body of work.
Guess Onaga only wanted to monopolize the cute Kashiwabara. But seriously, don't confess to your bully, even if he accept Kashiwabara that wouldn't have been a healthy relationship.
