So Cute It Hurts!!

Synopsis

Twin siblings Megumu and Mitsuru Kobayashi attend separate single-gender schools. Seeking more diverse social interactions, they swap places without anyone noticing at first. However, their plan becomes complicated when romantic entanglements arise. Megumu, posing as her brother, confesses to and kisses upperclassman Aoi Sanada, who has always felt uneasy around girls. This encounter makes Aoi question if he prefers boys. Simultaneously, Mitsuru, disguised as his sister, gains the attention of the aloof school queen, Azusa Tokugawa, who experiences unexpected feelings during a moment of vulnerability with Mitsuru. Both pairs develop affectionate relationships, but the truth about the twins' switched roles stays hidden.
