I think you said it perfectly for the situation. Alex is obviously scared to fall in love again so we do have to look at his past to see what happened. He needs to open his heart up and be able to trust at least one person and DG might be the one to do it. Kudos for you comment.
It's creepy in almost every manga/manhwa, in fact. This persons' presence brings always problems
Hah, I know right.
Thanks for your input, I believe you've put even more sense to what I've been trying to get across.
What a shit parenting skills.
As for some people in the comments getting panties twisted. This is not supposed to justify his actions but put an insight as to what affected him, as well as show off exactly what happened with that man who broke him down.
By the way, anyone always gets this uneasy feeling whenever introduced with such smiley, angelic,cutesy character or so it seems? I have trust issues with this type of individuals in mangas by now. Lmao.
