Your description makes me curious about the story too ヾ(☆▽☆)
Agree, very curious
I remember it being very interesting and believe it or not I actually picked it up from the public library maybe I’ll look there again and see if I can scavenge for it if no one here knows what it is.
Okayyy hit me up if you find it!
I FOUND IT! It’s called Nightmare Inspector: Yumekui Kenbun (๑•ㅂ•)و✧
I beg, I can’t remember its title or too much about it, but I read it years ago and have wanted to read it again since. What I remember is the mc is a young boy (iirc) or at least has the appearance of one, and they’re in shop that’s Victorian-era like? I remember they follow customers into either their dreams or nightmares, and the person having said dream sees horrors they didn’t want to face??? Or like, events that they don’t want to happen to acknowledge have happened (this part’s a bit fuzzy). I can’t remember if the mc ate the nightmares or some form of them after but yeah if anyone may have a clue, I really appreciate it （/TДT)/
