Sankaku no Kyori wa Kagirinai Zero

"Which version of me do you love?" It is a question no one should ever have to answer, yet it defines the protagonist's entire existence. The girl he fell deeply in love with is not just one person—she is two. Sharing a single body but harboring split personalities, she exists as both "Akiha" and "Haruka." Faced with this impossible reality, he made a conscious decision to treat each personality as her own distinct individual, attempting to navigate his feelings for them separately while respecting their unique identities. However, maintaining such a delicate emotional boundary proves far more difficult than he ever anticipated. What begins as an unconventional attempt to honor both sides of the girl he loves gradually spirals out of control. His careful effort to keep his affections neatly divided soon twists into a bizarre and entangled love triangle, complicated by the undeniable fact that both rivals share the very same heart and mind. Caught in an increasingly surreal romantic dilemma, the protagonist finds himself trapped between two halves of a single whole. As the lines between Akiha and Haruka blur and their mutual affection deepens, he is forced to confront the agonizing weight of their ultimate question. In a relationship where the distance between three hearts is virtually zero, choosing one inevitably means losing the other.
