Then he should know better what his friend needed the most. You know, what Joohee said about Yuri keeping everything to himself and what Jaerim said about Yuri pretend to be tough guy when he is not. Forgetting? He never forget that why he treats Jaerim like that at the beginning and the end. It's Jaerim who actually makes him open himself just a little a bit and makes him happy, smiling, gentle. The changes Joohee talked about. I just wish he could help him a little.
People can't think that far ahead, Dunno is trying to do what he can to protect Yuri from being hurt right now.
Plus Yuri has been on the edge for a while so it's honestly a good idea to give him his own space for now instead of exposing his weakest part.
But honestly I think it's a good idea to make Yuri talk about it with someone but it isn't that easy and it leaves him vulnerable which is so far Yuri's biggest fear.
I HATE THAT DUNNO GUY! HE'S TOO MUCH. HE SHOULD HAVE KNOWN ONLY JAERIM CAN HELP YURI, YES ONLY JAERIM. JOOHEE BELIEVE THAT TOO. UGH!!
