DAMEO NO SHIINA-SENPAI TO YABAO NO SASAKI-KUN

Sasaki is a boy who is madly in love with his senpai, a known delinquent, which only makes Sasaki love him even more! Shiina changes girlfriends more often than his pants, but that doesn't stop Sasaki from confessing 160 times and counting. While Shiina tries to get Sasaki to give up, Sasaki is in love with this bad boy and won't give up until he wins him over. — Description from AniList community (anilist.co).
