Since childhood, Hiroi has shared everything he loves with his best friend, Take. This sharing extends beyond objects to people, including past girlfriends. When a former classmate named Mine confesses his lingering feelings for Hiroi, Hiroi agrees to date him but with a crucial condition: Mine must also accept Take as part of their relationship. Deeply in love with Hiroi, Mine reluctantly agrees to this unusual arrangement.

The story follows this trio of classmates as they attempt to maintain a delicate balance. The narrative shifts perspectives among the three, revealing their distinct inner thoughts. Hiroi is the driving force behind the polyamorous arrangement, a selfish and pushy individual who genuinely questions why relationships involving three people so often fail. Take, the childhood friend, has always passively accepted whatever Hiroi gives him without developing personal attachments to the people they share, though his feelings begin to change. Mine enters the relationship wanting a conventional romance with just Hiroi and initially resents Take’s presence, viewing him as an obstacle.

The precarious equilibrium of their relationship slowly becomes unhinged as subtle shifts in feelings emerge. As Mine and Take spend more time together, their initial animosity gives way to a genuine, unexpected connection. For the first time, Take finds someone he truly cherishes for himself, not just because Hiroi does. Meanwhile, Hiroi, who never minded when his past girlfriends preferred Take, becomes jealous as the bond between Mine and Take deepens. He realizes this possessiveness is precisely why polyamorous relationships are so difficult to sustain, yet he cannot bring himself to let go of either person.

The title refers to a moment when Hiroi buys three different ice cream flavors, which serve as metaphors for the three characters. The story is described as psychological and dramatic, exploring themes of possession, jealousy, and the instability inherent in nontraditional relationships. The narrative is noted for its open-ended conclusion, deliberately avoiding a conventional resolution to the trio’s dynamic. The manga was completed in a single volume and received the chil chil BL Award for best original manga in 2014.
