He just messed up

I don't think he's a bad guy, he just really loves her but has an odd way of expressing. I feel so bad for him, I was team yul all the way. I Hope he gets help and maybe they can still happen... he did stick by her side. It its't the ending and things could change, like how it takes an unexpected change. Also guys always say they want ''one'', but fuck it up. Sorry but I just think her ending up with the other guy is so typical, once an f boy... always an f boy. Also guys I understand he is creepy but he never once hurt her, even when he had the chance. He didn't even hit her when she bite her, he just doesn't understand he is being pushy. Yul reminds me of a puppy who keeps coming back, its kind of breaking my heart. Freaking didn't understand he was just coming out strong. ╥﹏╥
