Aimi is a popular college student with a reputation as a self-aware playboy. He dates anyone who accepts his terms: no exclusivity, no jealousy, and no interference with his other encounters. Kaede, a gentle and earnest underclassman, confesses to Aimi and agrees to every condition, asking for nothing in return. The story follows their unconventional relationship as Aimi, accustomed to shallow connections, grows unsettled by Kaede's unwavering acceptance. When Aimi deliberately kisses a sex partner in front of Kaede and receives no reaction, he begins to feel an unfamiliar possessiveness. His confusion deepens as he finds himself watching Kaede, feeling jealous over innocent interactions, and questioning why Kaede does not demand more. The narrative traces Aimi's gradual shift from emotional detachment to genuine attachment, culminating in his first sincere romantic confession. The setting remains grounded in everyday college life and Aimi's apartment, with the tension driven by the contrast between Aimi's calculated emotional distance and Kaede's quiet, unconditional affection. The key arcs include the establishment of the conditional relationship, Aimi's escalating frustration and jealousy, the breakdown of his defenses, and the resolution where he finally learns to express love without conditions or cynicism.
