Hi all, looking for a bl manga from several years ago about two college/university students who don't get along but somehow hook up. The shorter guy's ears kept turning red as he fell for the other guy who was known as a player and I think got slapped at one point by a girl. If I recall the cover had the blushing ears guy wearing a winter hat, title was mimi something, like ears don't lie maybe? If anyone can tell me the title and/or mangaka name that would be amazing!

Nvm, found it! Mimitabu no Riyuu (A Reason for Earlobes) by Kunieda Saika https://www.mangaupdates.com/series/8cxdliv/mimitabu-no-riyuu
