He was tied up to a shitty person who treated him like shit and didn't listened to his desire
Not sure its better but eh, wasnt his grandma ╮(￣▽￣)╭
Without being tied with his grandma?? What a mental, Dan can just let his grandma die tho but he can't coz he don't want to be alone.. and the reason why Dan fall for horsey here is because of the tot that he is "needed" by JK and the feeling of having someone by their side so when he JK slaps Dan with the truth that he is no longer needed then bam, all Dan's illusion was destroyed. Horsey here takes advantage of that.
Dan is not suffering because he have a grandma that needed him but when his grandma no longer needed him.
I don't care what y'all think, I'm just really glad Jaekhyun found him in time. Dan deserves better and deserves to live without being tied to his grandma and let's be honest, the only time he felt he wasn't really tied to her was with Jaekhyun
