Hyunwoo was really vague , he couldn't possibly be in a healthy relationship with a person with serious self-acceptance issues like subin
Sub in would never be satisfied by his vague actions , it is not about how young hyunwoo is , he seems like that in his he deals with his problems in general (u see , HE WAS SURE ABOUT HIS FEELINGS TO NOONA , ) and was vague after he told her , he seems to be inside his mind rather than outside his mind making action
It wouldn't work , subin would be insecure most of the time , and fucking afraid of the future with hyunwoo , he would be miserable ...
As I said before he only came out and looked at his footprints , he didn't actually chase him , or he would have caught him , like dude the footprints are there , and sub in was walking not running ...
He was always half hearted , and that would have been really unhealthy for subin ,

lmao wtf was that ending it came out of nowhere whole plot gone to shit and everything wasted like why even have the panel of hyunwoo chasing after him for what? realistic my ass its not a good endinf just bc its realistic like the ending doesnt make sense why spend ur time going into hyunwoo and subins rs if it was heading in this direction like hsdff wtf but moving on!
