Hana yori Dango, Cutie Boy Recommendations
The female leads are similar as they are pressured by their peers (at different levels of severity), they get called average by those surrounding them (looks, grades, etc) and share similar love interests. Yoo-Min and Tsukasa both bully the girls they love without realizing the troubles they're causing and are leaders of groups which are notorious within their area. There are also some similar plots, such as the female lead being kidnapped in a revenge plot against the male lead then get saved by the male lead.
Yoo-Min and Tsukasa are really alike. Especially that they bully girls they love. Heroines and plot are similiar too.
