omg yes!! thank you so much!!
I keep thinking it was Arisu or smt! no wonder I couldn't find it XDD Thank you!!
I don't really remember much of the plot but--
MC's sister was hospitalised and in coma (i think) and so the MC's pretended to be her sister and attended school for her.
Her class seems to be playing some game or smt?? And that whatever they wish would come true.
I remember there was one chapter whereby someone's house got caught on fire and the mastermind (??) told them to dive into the fire and save the citizens. The mastermind was never revealed until the end.
Her sister seems to play a key role in the game. I think she's one of the founder or so-???
The MC was trying very hard to stop this entire mess.
