Koi Lemon.

For as long as he can remember, Tamaki has lived behind an invisible barrier. A rare and isolating dermatological condition causes him to break out in painful hives at the mere touch of a girl's skin, turning everyday interactions into ordeals and rendering romantic contact a distant, unattainable fantasy. His world has consequently narrowed to the safe, predictable confines of his room, where he finds solace in the fictional heroines of adult visual novels—particularly Lemon, a character whose charm has captivated him completely. Tamaki's stagnant existence takes an absurd, bewildering turn when his sister, in a misguided attempt to address his physical frustrations, ships him a life-sized, anatomically detailed doll. The intended purpose is embarrassingly clear. However, the moment he lays his hands on the package, reality warps around him: the doll stirs to life, breathing and moving as if made of flesh and blood. To his utter shock, her face is not a random design but the spitting image of his beloved Lemon-chan, pulled straight from the pixels of his favorite game. Now, Tamaki is confronted with an impossible dilemma. The girl of his dreams is standing before him, yet the very core of his curse remains—skin contact with her, real or not, could trigger his agonizing allergy. With his sanctuary turned upside down and his deepest desires walking around his bedroom, he must navigate the surreal chaos of living with a fictional character made real, all while grappling with a condition that makes even the simplest touch a potentially painful gamble.
