Title of a manga

Hey so I’m trying to look for a manga but I don’t remember the name. I usually read bl manga but the one I’m looking for is a shoujo manga. There is this one scene where the guy (the bf) ditches the MC at a train or bus station when they were supposed to go on a trip for winter and he goes with another girl from his past because he wanted to help her or something. I remember the male lead had black hair and the female had light colored hair. Pls help find this manga if you can
