What is even so indecent about this...didn't anyone have a doting cousin? It's like that to me.
To think this far in the manga is something disgusting surely means that you guys heads are more or less effed up.
Because...it's just the older guy (who's also under 18) thinking the younger guy (10) is cute and nothing much, but the younger guy is confused.
Everyone hates this but Rui's case was not so stupid, he had waited to love his teacher legally but refused to realise that the sensei decided to end things with him, and before he could stop anything his sensei left him...
When Kazushi saved him, he couldn't suddenly move on from yearning for his sensei but always regretted being with Kazushi...until he was saved again he got over himself and loved the guy in front of him.
The pacing of the character development of Rui is natural and I don't mind at all, most of the mangas written by this author don't just follow the cliche yaoi ending, it concentrates upon a particular character as a whole.
I don't care how dark it gets (if something like Killing Stalking is popular) I'm interested in unusual mangas so 5/5.ヾ(☆▽☆)
