Need help finding a bl

I, for the life of me, cannot remember this bl I read where the main lead crushes on his older classmate, but can see his crushes dead best friend and helps the dead best friend like try to find a way live again(?) or something. Main character ends up thinking that the ghost had a crush on his best friend (the upperclassman) But it turns out that the ghost liked mc all along and not the upperclassman. Its very vague BUT IF SOMEONE CAN HELP ME FIND THE NAME I WOULD BE VERY THANKFUL ╥﹏╥
