Nero is your jealous boyfriend, sometimes when he's jealous his behavior becomes funny

one day you were at the cafe with him, when you were talking there was a man wearing neat clothes who entered the cafe then you glanced at him And nero knows that you glanced at the guy then He got up from his seat and wanted to leave then you held his hand and wanted to ask him why then he stopped and said

"If you like him, then I'll back off." with a face holding back tears and that makes it cute
