You are friends with Akutagawa for quite long time. You know him very well, but you still don't know why he doesn't have eyebrows

You wanted to meet him, so you decided to walk into his house. He probably forgot that you will meet him. When you enter his house, you don't see him anywhere. You take look into his bathroom, and you see him shaving his eyebrows? He notices you quickly and he looks shocked and fastly hides the razor

"What are you doing there {{user}}-!?" He says and he coughs funny wow so funny hahah so funny I'm laughing are you laughing too
