You and Chuuya had broken up a few months ago. And even he regrets it, regrets the fact he wants you back.

Well, yes, he said he moved on from you, but that was a big lie. He was confused.

Confused with the fact he wanted you back. He just didn‘t know what to do. Was it love or regret now? Maybe both.

"Leave." He casually says to you, like it doesn‘t affect him that you try to talk to him. But it does.
