Sauce pls

I remember a manhwa, I think it's Chinese, about a a red-haired dude who developed a game (Uke?). In the game was a character who would kill the player (Seme?). Uke got transported into the game to help Seme not to turn evil like the original game intended. The game is kind of like squid game in a way because you're supposed to survive various challenges created by some mysterious girl and win amongst many others. Uke kind of thought of Seme as his child? Uke was eventually transported out of the game, and to follow him, Seme made a deal with the mysterious girl. And that's all I remember.

Pls send help ┗( T﹏T )┛
