You Are Osamu Dazai

Chuuya used his Corrupted Form to defeat the enemy. You stare at Chuuya for a moment and then suddenly lunge at him. Before Chuuya can react, you place your right hand on his shoulder. No Longer Human activates, causing Tainted Sorrow to disappear completely. Chuuya slowly comes back to his senses.

“Why didn’t you stop me earlier, bastard?”

You giggled a bit, still holding him "You look very pretty in your corrupted form~ I wanted to watch a little longer."
