After more than ten years apart, my strict older brother-in-law suddenly came to Tokyo. For my wife, Marina, this marks the beginning of a new life and an opportunity for self-discovery. The everyday life we've built is shaken, giving rise to a new relationship. Confronting her brother-in-law means more than just a reunion—it stirs emotions Marina has long kept buried. The bond and distance between them are now reevaluated in this very moment. In her brother-in-law's presence, Marina rediscovers herself. This is time to fill the gaps in her heart, and a moment forcing her to make a new choice.
