I'm looking for a yaoi manga from a while ago, it had a convenience store or bookstore setting, the uke was working there, then the seme confessed to him but the uke thought he was playing a prank and got mad. Then the seme started working there and they fell in love. The seme was super shy and his behind his hair. I think he cried a lot too

Kiss Shite Yowamushi-kun! maybe?

Yessssss! Thanks so much! ☺
