No he's just a delusion made by Myeonghan's mind as a coping mechanism but after seeing Seungchan he realised that it was all just a delusion. (⊙…⊙ )

I'm so happy to say he isn't a ghost - Sihoo (pink haired dude) actually exists. When they were younger he was involved in a serious accident which led to the MC believing that he had died. Due to this the MC had delusions that Sihoo was alive all along that's why people bullied him because he was speaking to himself all this time no one was there. As the manga progresses the MC's mom tells him everything that happened and he meets up with the real Sihoo. My explanation may be shit and you may not understand so just read on (￣∇￣") ╮(￣▽￣)╭
So im on chapter 11 and im confused is the pink hair guy a ghost?
