@Le*** it's actually an easy plot to understand but due to the story being in game verse some might find it confusing. To put in simple words, this manhwa is about a game Dreadful Night a typical teen-age horror game. Our MC here stucked in this game. For a long time that he's not even flinch if he died. Our ML on the other end is determine to stay with MC but he kept hiding something from other. 

So to explain what's happening now, all of this NPC became Players when they insert their respective tapes. Bada didn't enter the game yet. All of them died numerous time to get 1 ending. So they decided to ahut their tape and reset back to NPC forgetting all the painful memories. On-the-other hand, Seongchan(glass guy) and Doha(MC) Has been together but due to some unstated fact they went their separate ways. Now Bada(green hair) needed to be very sneaky in order to understand what our MC(Doha) been doing. YongTaek(red hair) wanted to shut off after sharing all the clues and the things he knew.
