Well, perhaps it's a story where the main characters receive an invitation to a 'creepover', which might be like a sleepover but with a creepy or mysterious twist. The graphic novel would then show their experiences during this unusual event. It could include things like exploring a haunted house or encountering supernatural beings.
There could be a diverse set of main characters. Maybe there's a young girl who is the first to receive the invitation and she drags her friends along. One of her friends could be a bookworm who tries to rationalize the strange events using knowledge from horror books he has read. Another could be a joker type who initially makes light of the situation but then gets really scared as things start to get serious. These characters would then drive the plot forward as they navigate the creepover in the graphic novel.
I'm not sure specifically as there could be many different 'creepover graphic novels'. It might be about spooky or mysterious events that happen during a 'creepover', which is like a slumber party with a creepy or thrilling twist.
I'm not aware of a very well - known 'creepover graphic novel' series off the top of my head. But there are many graphic novels with spooky themes that could potentially be considered in the same vein.
I'm not sure who invited you in manhwa 32. It might be a plot twist and we'll only find out as the story progresses. Maybe it was someone we least expected!
I have no clue who invited you in that particular part of the manhwa. It could be a new character introduced just for this twist or an old acquaintance with a hidden agenda.
Hard to say exactly who invited you in manhwa 37. It could have been a friend or an unexpected ally. Maybe you need to re-read that part to figure it out.
