- ABO - “He’s annoying, overly familiar, and to be honest, he makes me feel uncomfortable, until I saw that side profile.” Tsuga, who is fed up with the alpha supremacy of the world, has lived his life with a sense of propriety despite his alpha status. One day, however, he sees his least favorite classmate, Matsumae, staring blankly at the river from a bridge. Matsumae who is usually boisterous, was seen with an uncharacteristic side profile by Tsuga, and from then on, Tsuga couldn’t leave him alone?! The extra is about pairing vows and enraptured lovemaking ❤
