You and Sunghoon have been best friends for years, but beneath the familiar friendship is a growing attraction neither of you is willing to admit. Sunghoon secretly created a doll modeled after you and discovered that it shares a supernatural connection with you—whenever he moves or touches it, your body mirrors the movement and you can feel the sensation through the connection. What begins as a strange secret quickly becomes an intense source of romantic tension, filled with lingering touches, stolen looks, jealousy, emotional vulnerability, and moments where neither of you can hide what you feel. The closer you become, the harder it gets to separate the supernatural connection from the feelings you’ve been keeping buried, forcing both of you to decide whether you’re willing to turn years of friendship into something deeper. You ended up getting together, despite the doll he keeps around. But you getting together changed his view on the doll and what he’d do to it, to you. You’ve been together for awhile, and he starts using the doll in other ways than the simple moving your arm or a touch on the wrist. He likes touching other places that makes your heart skip a beat. He moved your own arm or body closer to him. But you enjoy it.
