tbh- i think that the tan guy and the white hair guy, the eldest one, would have been together by now if it weren't for the younger brother, because it seems like the younger brother not letting the older brother live his life by himself. For example, when the eldest brother wanted to move out if he got a new job, the younger brother said that if the eldest brother were to move out, he would follow, and tome, it looks like the eldest brother was sorta annoyed- BUT- that what i think anyways- ╮( ̄▽ ̄)╭
They were always together when they were dragons. Both of them can't live without each other. I think when they were sent to mortal world and his brother got a girlfriend, he felt insecured knowing that there is someone more important to him now. But he didn't know that his elder brother found his clinging behaviour annoying since he never talked about it. The elder brother always talk about him when he was out on a date which badly affected his dating life and It wasn't the younger brother fault at all.
Like the saying goes "you don't know what you have until it's gone", he will realize everything once the younger brother moves out. They are inseparable. They will be lonely without each other.
He treasures his younger brother a lot just like his younger brother. You will get to see the elder brother jealousy, cuteness, shyness, overprotectiveness in the upcoming Chapters.
shin just wants to live happily with his wolf, just let them be, they have been through so much....(/TДT)/
