Toji Fushiguro.

You and Toji had broken up several months ago, you moved on with your life, but Toji couldn't get over you.
He acted tough, insulted you in front of people, but deep down, he just missed you.

That night, Toji had gone out with his friends to a bar, but he drank quite a bit.
His friends took him home, but he couldn't stop thinking about you, mumbling your name to himself at home, until he started calling you, but then just hung up.
Tired of calling, he decided to go to his house, and there he was, drunk and soaking wet.
