Aru Oshiire Atama Otoko no Hanashi: Mokuhan Mangashuu

"To me, vanishing was eternal release."

A man who left his father's house lost interest in studying, lost faith in humanity, and locked himself in his apartment. So a year passed alone. Everyday, he thought more and more often about suicide, but one day he looked in the mirror and was stunned: instead of a head he now had a wardrobe. His existence became like a wardrobe—small and closed to the whole world.
