Looking for this BL

Hello i read this story a while back but can’t remember the name.
To summarize it: basically it was a bl where mc friend died in an accident, mc kept like hallucinating him until one of his alive friends (which i believe was the ml) kinda snapped him out of it. There was also a time skip to college and ml was like a year older than mc.
It a manhwa. I dont remember if it has smut but i know later story was mostly just fluff with a bit of drama. ┗( T﹏T )┛
