I'll probably get a lot of down votes for this but I have to disagree with you. It's emotionally and mentally EXHAUSTING to have to keep reassuring another person that you love them and aren't going to leave them. Just to have them keep thinking you are. After a while you just need them to believe you. It's not another person's job to "fix" the depressive. Nothing in life is guaranteed, every relationship has the potential to be over one day, that's the risk you take. It's unfair to expect the other person to constantly be the depressives rock while the depressive is the other persons quicksand. If you keep pushing people away eventually they're going to leave you. They deserve to be happy too. I guess my point is if you suffer from depression, get help don't drag other people down with you.
Yes! And let's not forget Chun Sam had been kept living inside his house almost his whole life up until now with no type of social contact besides his parents because they were afraid. And if I remember (I think the last time I read the earlier chapters was in 2015?), most kids stayed away from him when he entered high school. He didn't really have anyone to communicate with and learn how to deal with others. I think Chun Sam is pretty strong for being able to stay by Min Gyeom's side.
The thing with depression is that you only seek for help when someone or something open your eyes and that's not easy. I've suffered from depression all of my life and I blame myself enough for not wanting to live that I don't really need someone else to drag me down. If you're not mentally strong to be supportive then help that person to get help but don't blame him for something that he already knows cause you're doing more wrong. That's a way of "victim blaming" and we all hate that. Because depression is considered a "sickness" even if it's "mental" and you don't go blaming people for getting sick do you?
BTW I get that that's what most people may think and it's not wrong, it's just that the way you put it is not taking into consideration the fact that being depressed is not exactly something we "choose" but something that "happens" to us. A big problem to solve alone. And yes, help is needed to overcome that. Leaving alone someone with suicidal thoughts is just leaving him the choice to die. Is exhausting, YES, of course. But if you love someone I guess you don't want him to die or to be unhappy. If you don't have the power to help or the ability to do so, make him realize that he needs to get that help somehow
Depression can't be cured with nice words and that's a fact. You can't expect a person who just few months before wanted to die to be suddenly okay and to not have trust issues when everyone around him used him. Blaming someone with a (mental health) problem for not being fine is just wrong. Yes, I can't blame our handsome vampire for being exhausted but he should try to understand the signals of "I need help, I need you to reassure me" that his boyfriend is sending. Because they're there.
The more a depressive push you away, the more attention you should pay to him. Don't just leave him alone with his thoughts cause obviously they're gonna be negative
