looking for this manhwa!!

a bl manhwa where working mc dies so ml lost it. mc was trasmigrated to the lone pink haired? student of campus where ml studies. mc thought no one would mourn for him coz he thought ml and him were just friends with a sunbae hoobae relationship. mc approaches ml as he was friendly with his og body and thats where ml notices that ogmc is in the pink haired when mc called out his name softly. ml also keeps mcs memento on him.
