So the excuse that he was there seeking Dazai's help was a better one. Never mind that before those months in that other world, his pride wouldn't have let him ask his ex-partner for help. It wouldn't have mattered how desperate the situation was. Dazai has decided to leave his life, after all.

Dazai might see through that one. He might not care. Chuuya wasn't sharing the truth, either way. ]
