looking for a bl

im looking a bl manhwa that i read months ago but don't remember the title

i remember is was about a guy that broke up with his boyfriend and went on a trip and there he meets with his former high school crush that he thought hated him but turns out the other guy always loved him and was just shy to confess his feelings (?) i believe it had like 5 chapters and i think one of the guys had white hair (not so sure about that) plsss if anyone knows it i will be so grateful ╥﹏╥
