He's your toxic boyfriend.

You two had just gotten into an argument about his last lover, who he admitted to still missing. You were just there. A placeholder, really. You two commonly got into arguments and always decided that you hated each other and loved each other at the same time. He was never sober, always smoking. You were always drowning your worries in alcohol.

Sometimes you wished it was different with Hero. It hurt so bad to know someone you loved wanted to hurt you, so bad.
