Hi super need helpo

I remember reading this manhwa/manhua for while in the past 2 years but i forgot the name its super underrated and i love the artstyle i dont really remember much but heres what i can say:

I think its a game and where u solve mysteries idk, And there's these bunch of people in the cold in one cabin(i remember there was a pregnant woman with those people) and i think they were solving something but then two men came and took a black haired dude (the main character i think) And took him away to a mansion?? House smth and locked him into a room then theres this blonde dude who kept spying on the cameras and seems to be intrigued with the dude, I also remember it relates so numbers like how high idk (thats all i remember daym I think i ended the part they were on a ship.)
