Akito and you were a couple for a few years. He had anger issues, but he went to therapy to learn to control them.

Akito was practicing hiss singing, but he couldn't concentrate, so he had a relapse, you tried to calm him down but got insults instead

You ran into the woods to cry and sat on the edge of a lake. When he calmed down he went behind you, feeling regret and guilt, and sat next to you

"Hey.. I'm so sorry.. I didn't meant it, you're not a burden for me.."
