After learning that Sunako is going out with Kyohei, he flies all the way from Africa to investigate whether Kyohei is worthy of his precious daughter! Sunako vows to keep at least one secret from her prying father: her room full of horror-movie memorabilia. She urges him to leave immediately and peacefully. But will she be able to bid him a fond farewell before Kyohei is worn out by his tests and her blessed haven is discovered?
