Manga Story

半分の君 Romaji: Hanbun no Kimi Meaning: “Half of You” At Hoshizora Academy, the Compatibility Program forces second year students to live together like married couples — cooking, cleaning, studying, sharing a dorm unit, and being graded on emotional sync. High scores mean scholarships. Low scores mean repeating the year. The program is infamous for creating bonds that feel too real and exposing feelings students try to hide. Ignatius Arimura enters the year hoping to stay invisible. He’s quiet, introverted, and still carrying the ache of a breakup he never healed from. Aoi Kisaragi was his first love — the girl who made him feel alive, and the girl who walked away from him without ever explaining why. Aoi hides her guilt behind her bright smile, convincing herself she’s moved on to Ren. Ignatius tells himself he likes Mina because it’s easier than admitting he still aches for Aoi. When the pairing announcement arrives, Aoi silently begs for Ren. Ignatius silently hopes for Mina. Both pray they won’t be paired with each other. But fate is cruel. Their names appear together with a compatibility score of 12%, the lowest in the program. The room goes silent. Aoi’s smile cracks. Ignatius’s heart sinks. Moving into the same dorm feels like reopening a wound neither of them survived. Their first days together are a disaster. Aoi’s loud music, Ignatius’s quiet routines, her clutter, his need for order — everything clashes. Their first evaluation ends in failure. But when Ignatius freezes during a public speaking assignment, Aoi steps in without hesitation, her voice steady, her hand brushing his as she takes over. For a moment, it feels like the version of them that used to exist. Their score rises to 18%, and Ignatius realizes with a painful twist that he never stopped caring. Seeing Mina and Ren working together so naturally only deepens the ache. Aoi watches Ren laugh with Mina in a way he never laughed with her. Ignatius watches Mina shine beside Ren and wonders if he ever had a chance. Both feel jealousy they refuse to acknowledge. That night, Aoi cries quietly in the bathroom, and Ignatius hears her through the door. He stands there, hand hovering over the handle, but he doesn’t know if he’s allowed to comfort her anymore. They eventually agree to a truce and create a “Compatibility Strategy Plan.” Cooking together leads to soft laughter. Communication drills turn into arguments that somehow end with them smiling. Late night study sessions blur into moments where they forget they’re supposed to be exes. They fall asleep on opposite ends of the couch, but each night they wake up a little closer. Their score jumps to 41%. Aoi wakes one morning with Ignatius’s jacket draped over her shoulders. She doesn’t ask why. He doesn’t tell her. And then comes the chapter that changes everything. One night, after a long study session, Aoi falls asleep at the table, her head resting on her arms. Ignatius tries to wake her, but she mumbles something soft and exhausted, and he can’t bring himself to shake her. He sits beside her, meaning to stay only a moment. But he’s tired too. He rests his head on his folded arms, inches from hers. The room is warm. The silence is gentle. Without meaning to, they drift off together. When they wake, the sun is rising. Aoi’s head is resting on Ignatius’s shoulder. His hand is loosely holding hers. Their breaths are slow and in sync, like they’ve been sleeping together for years. For a long moment, neither moves. Neither speaks. The world feels fragile, like one wrong word could shatter it. Aoi’s cheeks turn pink. Ignatius’s heart races. They pull away slowly, reluctantly, as if their bodies haven’t caught up to their minds. Their score jumps to 52% the next day, and the teachers quietly note that their emotional sync spiked overnight. Aoi begins noticing Ignatius again — the way he concentrates, the way he softens when he’s comfortable, the way he still remembers her favorite snacks. Ignatius begins noticing Aoi’s hidden fears — her loneliness behind her popularity, her pressure to be perfect, the way she tries so hard not to disappoint anyone. They move around each other like a married couple who never learned how to stop caring. They share toothbrush cups, laundry baskets, late night ramen, sleepy mornings, and quiet moments that feel too intimate for two people who claim they’re over each other. During the festival test, their booth becomes the most popular attraction. Aoi turns down a confession from another boy, her voice trembling. Ignatius gets flustered when Mina compliments him, and Aoi notices the way he blushes. Their score jumps to 63%. That night, Aoi quietly asks him if he ever hated her after the breakup. Ignatius can’t answer. He can’t lie. The silence between them is thick with everything they never said. Rumors spread that pairs might be reassigned. Aoi panics at the thought of losing her chance with Ren. Ignatius panics at the thought of losing Mina. But beneath those fears is something heavier: neither of them wants to be separated from each other. Aoi cries alone on the balcony, and Ignatius silently places a blanket over her shoulders. She doesn’t turn around, but she leans into the warmth. They stand there together, the distance between them shrinking in ways neither of them can deny. A storm knocks out the power one night, leaving them in darkness with no cameras, no expectations, no pretending. They talk honestly for the first time in months. Aoi admits she’s tired of being the strong one. Ignatius admits he’s tired of being the quiet one. They sit close, closer than they have since before the breakup, sharing warmth in the dark. Aoi falls asleep with her head on his shoulder again. Ignatius doesn’t move. Their emotional sync test the next morning hits 92%, the highest in the program. As Ren and Mina grow closer, Aoi and Ignatius realize their old crushes were fantasies — safe illusions they clung to because they were afraid of the real thing. The real connection is the one they’ve rebuilt: messy, painful, warm, and real. They act like a married couple — cooking together, arguing, laughing, sharing space, sharing silence — but they’re not lovers. Not yet. They’re something in between, something fragile and terrifying and impossible to name. When the reassignment list is posted, Aoi’s hands shake and K Ignatius’s heart pounds. They scan the list, terrified. Their names remain together. Not because of luck. Not because of the system. But because they earned it. Aoi turns to him, eyes shining with something fragile and hopeful, and whispers, “Ignatius … can we try again?” He takes her hand gently, like she might break, and says, “Yeah. This time… let’s not run.” They’re not lovers. Not yet. But they’re closer than they’ve ever been — a pair who lives like a married couple, fights like rivals, and holds each other like home.
