Pls help me

BL yaoi spicy manhwa, Ike has blond hair.

Manhwa taking place mostly on a train, and the uke has to find a jewel or a pearl or some sort. I do not remember much, but he gets blindfolded and gangbanged in the train carriage and then later “saved” by a random man. Then he kinda progresses in the train carriages into a more luxurious private train carriage with this random psycho man who then SM-style fucks him??

Anyone? Pls, I have this random urge to read it again but I cannot remember its name! (๑•ㅂ•)و✧
