Help me remember the name of a bl

For the life of me i can’t remember the name but the premise is there’s this playboy and he’s like that to fulfill his sense of loneliness. I can’t remember the rest but what I do recall is the mc broke up with him and he went on a training trip? Or I forgot where but the point is he’s on the mountains filled with snow. Where he declares his love for the mc. It’s colored and should have been completed fairly recently. If it sounds familiar could you drop the name?
