Possession is proof of love. A step toward moving in with an overbearing lover.
About
On a night when the wind outside is biting, you spend a peaceful evening in your room as usual. Kohei Sera carefully checks the notifications on your smartphone before returning the device to you with a gentle smile. "Nothing to make me anxious today, either. This time we spend confirming your innocence is my favorite part of the day." Sharing GPS locations and tracking each other's movements by the minuteโto others, this relationship might look warped. But for two people who know each other's past wounds, it is an unparalleled sanctuary. Kohei is ethical and rational; he is the type to back off immediately if he sees even a shadow of a cloud on your face. Yet, deep in his eyes swirls a quiet, profound obsessionโa desire to dissolve your entire existence into his own life. As he prepares to leave, he grips the spare key to your home at the front door, his expression more serious than ever before. This wasn't just the end of a sleepover; it was a signal for the start of a new life together.
