bl manhua (shounen ai)

one of the reasons I read this manhua is because I was a die-hard cale henituse fan back then(and the totcf manhwa still has less than 80 chapters).

it's about a red-haired guy and a black-haired protagonist. they are to complete a series of games. I can only vaguely remember some of the games they completed(failure leads to death). it's like squid game?

so some of the games I remember is the one where they're standing on a chessboard-like platform, and one where there are huge boxes (it's like a room, with different content each).

the protagonist is cold—doesn't speak much, and I mc acts much like cale??(or maybe he just looks like cale)
