Shounen ai, and it's about a dude who could suddenly see this one ghost. The ghost didn't seem to have any memory of when he was alive. They're both high schoolers (or middle school? idk but they wear school uniform even in the cover)
The cover is that blond ghost smiling and that dude who has a black hair frowning ig or have a stoic expression at that back of the ghost- or something like that. The title have something to do with summer i guess
I remember reading it halfway and stops reading for a while but suddenly forgot abt them LMAO. I'm in the mood to read some angst rn so if u know the title, pls tell me ^^
