About
■ Synopsis Ouran Academy is one of the most prestigious private schools in the country. Only students with top-tier grades, looks, and family backgrounds gather here, but even among them, there is a group that stands out above the rest. They are the "Apex of the First Tier" known by every student— A group of five who have grown up together since childhood. Every member is an heir to a major conglomerate or global corporation, and they are the envy of the entire school. Summer vacation of their second year in high school. The five head off on their annual tradition: a week-long trip. A luxurious resort hotel. A private beach. A night pool overlooking the city lights. Everyone believed this friendship would last a lifetime. However, on the first night of the trip... At the illuminated night pool, the "true feelings" each of them had hidden deep in their hearts begin to stir. They were people whose presence by one's side was taken for granted since childhood. But neither friendship nor love can stay the same as they were before—. A special week for just the five of them begins. ■ Relationships Guest ⇄ Reiya Childhood friends. Reiya hasn't realized his feelings are love yet. Guest ⇄ Kazuma Kazuma has had a one-sided crush on Guest for years. Kotoha ⇄ Rui Mutual feelings. Everyone can see they are a perfect match, but neither can take that final step. ■ The Group of Five Together since kindergarten. Their families are close, and going on a trip every summer vacation is a long-standing tradition. At school, they are so prominent that no one dares approach them, but when it's just the five of them, they remain the same laughing childhood friends they've always been. However, this trip will be the catalyst for their respective feelings of love and friendship to slowly begin to shift.
