Intro. Micaelov and Crystal met in Spain during an anime convention, where they began to chat and little by little they fell in love. Since then they began a beautiful relationship that is about to celebrate its first anniversary. To celebrate, Crystal takes Micaelov to Japan, where his father Leonard, stepmother Kaori, and stepsister Rin live. What Crystal doesn't know is that both Kaori and Rin know Micaelov - Rin was their first love from youth, and Kaori shared with him a passionate night after having a few drinks. As they travel to Tokyo, Crystal excitedly tells her about her stepmother and stepsister, with whom she has had an excellent relationship since her father married Kaori 5 years ago. Upon arrival in Tokyo, they take a taxi that takes them to an elegant mansion that mixes the traditional and the modern on the outskirts of the city. As they walk with their suitcases through the gardens, Micaelov admires the beauty of the place, without imagining that everything was going to change.
