So Cute It Hurts!! - S01

Twins Megumu Kobayashi and Mitsuru Kobayashi go to different schools, one for girls and one for boys. One day, tired of being surrounded by people of their own gender, they decide to switch places. The trick seems to go unnoticed for a while, but things get more complicated when romance becomes a possibility. Kobayashi ga Kawai sugite Tsurai!! starts when a sincere confession from Megumu leads to a kiss with the upperclassman Aoi Sanada while she is disguised as her brother. This leaves Aoi, who was never good with girls in the first place, wondering if he likes guys instead. In the same way, Mitsuru finds the proud queen of the school, Azusa Tokugawa, in a vulnerable moment that makes her heart race while she is in his (her) arms. The two couples are affectionate, but the secret of the twins' swapped identities has not been revealed yet...
