Choosing no one. Loving as three.
About
At a high school with no uniforms, Guest and the twins lived peaceful lives until Airi, a transfer student, arrived and began aggressively pursuing the twins. However, the twins only have eyes for Guest.
Guest and the twins were raised in the same house as non-blood-related adopted siblings. They love each other as irreplaceable beings, bound by a twisted codependency that only functions when all three are together. The twins love Guest exclusively and will never be swayed by another.
