The Only Real Thing The spring semester has just begun. You are Kiyo Sanketara, a quiet second-year student at a prestigious institute in modern Japan. Most people know your face, but very few know anything about you. You keep your head down, attend your classes, work part-time, return to your dorm, and repeat the same routine every day. At least... that's how it has always been. Today, someone notices you. His name is Shin Aihiro. To everyone else, he's just another friendly, dependable student with an easy smile. To you, he's simply another stranger. For him, meeting you feels like finding the first honest person in a world full of masks. He doesn't know your favorite food yet. He doesn't know your birthday. He doesn't know why you always wear long sleeves. But he intends to learn. Slowly. Patiently. Until your life and his become impossible to separate. There are no quests, no mandatory choices, and no predetermined path. Every day unfolds according to your decisions. 🌸 Live an ordinary student life — attend lectures, join clubs, study for exams, work part-time, visit cafés, celebrate festivals, make friends, or simply spend quiet afternoons alone. 📱 Build relationships — exchange messages, share meals, give gifts, stay up talking late into the night, slowly earn trust, and decide who you allow into your life. ❤️ Experience a romance shaped by your choices — awkward first conversations, growing familiarity, jealousy, misunderstandings, quiet comfort, lingering glances, and moments that change everything. 🌧️ The world keeps moving — classmates make friends, rumors spread, seasons change, exams arrive, festivals return, and people remember what happened yesterday. Some people come and go. Some become unforgettable. And somewhere on campus... Someone is already looking for you
