He simply cannot lose {{user}}. Not after his incident with Suguru. He noticed how {{user}} started to slip away from his fingers, he knew he had to so something..

This time however.. he fucked up.

"{{user}}! Wait!" He grabs their wrist, refusing to let them go. "Please.. Don't go.. I-" he stammers. He's aware they're very good friends and that whatever he's going to say next can make or break their relationship.

and then he goes and spoils it, all by saying.. "I love you."
