He insists that Chi Songliu has left him physically and mentally exhausted, unable to live or die, and demands that Chi Songliu take responsibility. Chi Songliu thinks: What kind of lunatic is this? Get away from me. The boss Dazai thinks: You bastard, you did something terrible and won't take responsibility. You're done for.
