It's a story about a necromancer (in a game form) bringing back to life really good players who were betrayed and they end up plotting against the traitor by reviving each and every one of the betrayers. I think the main antagonist's name was Bae Jaemin? Anyways PLS HELPP

I don't remember the details that much but I really want to reread it, so basically there are two characters, a black-haired one, and a ginger (?) haired one. The ginger haired one is a taekwondo student and he wants to quit, and thanks to the black haired dude he quits. And then suddenly the black haired guy disappears, leaving the ginger hair heartbroken. And if I remember correctly, that manhwa mentions a song by Coldplay (Everglow) somewhere in the chapters. If this sounds familiar please tell me if you know it!
