is he going to ask why he's the only one who can see him because srs why can't no one else...

That is the power of destiny and they are meant to be with each other.

This!

I figured he could just choose who can see him (more selective) and who can't (kind of why there's been so many employees scared away because of the ghost and the rumors circulating that bring in the customers. I definitely dont thing Sungwan is the only one who can see him though.

if there r meant to, then why will ghost-san pass on after the wishes...

That would make a lot of sense, thanks for the insight. My brain is too foggy at 1am when I usually read to realise these things lmao

I read it at 2:45 AM which is my prime thinking time. Thinking too deep is for my late nights
