Yohan could have got minjae if he weren't such a abuser no matter what I can't get the fact he beat him up till he almost died he was on drugs so he lost control so what ? Author made it that Yohan life got better cuz he stopped his messed up lifestyle but his mind still filled with minjae in guilt , characters are very realistic on the same note i get frustrated by their behaviours taehwan is no different but he was just a teenager himself what he could have done this story I read out of blue and there is nothing romantic about this manhwa it's filled with life pain and sufferings, guilt and getting your shit together after becoming adult i don't know what more to say their bystander friend is only fun thing in this.
