Otome Yankee wa Unmei no Hito wo Matsu
Delinquent/Tough guy likes cute things, went to see a fortune teller who told him he'd meet his destined one on the way home, who just so happened to be a fellow classmate. This classmate actually already had a crush on this guy. Kinda anti-climatic, no real drama.
Confession from Tomorrow
MC gets confessed to in middle school, rejects the guy, but now they're back in the same class, and MC had developed a crush. However, turns out this guy is actually the twin brother. Very cringey, only one main jealous scene, and lots of plot holes. rip.
