The manga he needs to end in an abrupt way is Q and A. The scanlators have stopped at 10, and I can't say I blame them. I got 12 (having missed 11) before Raw Paradise went down. He needs to abandon that mess and start a new weekly seishun drama pronto.

I wonder if the relatively relaxed atmosphere of Katsu doesn't reflect a reaction to what happened with H2: perhaps a determination not to paint himself into that corner again.
