Why do yall want Dan's grandmother to die so much !?!?!?!

Because she's the only reason left for Dan to stay with him and put up with all this abuse.
Nobody wants her dead.
Dan has two reasons to stay with Jaeshit: his grandma and his feelings. His feelings have been trampled on one too many times, and I'm sure he's understood that his love will stay onesided. If the grandma dies, there'll be no more reasons to stay with Jaeshit, since there won't be any hospital fees to pay anymore.
The reason why everyone thinks her time has come is because we've seen Jaeshit seem a good person when he was with the grandma. I don't think Dan just leaving or not answering the phone would make him go "what?" in shock, he'd probably think he'll come back because he needs the money.

Its the better for him
He still need to pay her grandmother's surgery thats why he needs money, just imagine how expensive it is, by selling his body and being a slave to jeakyung.
So if his grandmother is gonna die,
he no longer need to pay the massive bills in the hospital and
He no longer need to work in that hell hole where he suffered.
He can now rest and enjoy his adulthood.

I decided to bite the bullet read try to read the story and skip the weird part and it's overall weird. It's trying to make the adult not seem so bad because it's "true love" even tho when he fell in love with the main character, And the adult st the time was in like late middle/early high school. And the main character was in elementary
I love how this is number 2 for top yaois and we all know it's not because it's good
