The primary thing here isn't that they need communication 😠the whole reason seo hasn't responded yet is that he wants to sort out his feelings, especially considering his insecurity. Yes yongchan alr knows abt his short temper but it's another story when the person is dating you, because you're gonna be with them constantly. They'd be seeing each other way more than they already do. I'm glad he's taking his time I do feel for yongchan but rushing thing isn't exactly a solution is it?
