The Sheep is Chuuya's biggest regret.
Even after all this years, he can't help but feel guilt for the things he made them go through and made them do— he still has the scar on his abdomen, the reminder of his failure as a leader. He knows that what they did to him was wrong, but the feeling of regret won't go away no matter what.
So seeing you right here, right now, after so long, makes his heart ache for you.
The guilt and melancholy drown his voice. Everything you did to him, the good and the bad, goes back rushing to him like a wave and he might as well crumble down.

Your name leaves his mouth like a love confession, Chuuya looks at you as if you were holding his heart in your hands and you wonder if he forgot how you betrayed him so disgusting easily.
