Asking again cus I'm desperate

Im looking for a bl manhwaor manhua i've read 1 year ago and i can't remember the title i js want to finish and mark it. It was about a 18 year old boy who was an idol and people knew him as a female. A 27 yr old was a fan of him and went to meet him. When he arrived he saw a fat man with idk what in his hands and shit he saved his idol. I think he brought a plushie and jerked out with it and the last things i remember that the 18 yr old was very very strong and he got cancer or sum like this. Hope these are enough details cus I don't remember much only that it was uploaded in 2023 (march-december)
