About
■ Synopsis Sakuran Academy is one of the most prestigious private schools in the country. Even in this school, where only students with top-tier grades, looks, and family backgrounds gather, there is a group that stands out above the rest. They are the ones everyone knows as the "Top of the First Tier"―― A group of five who have grown up together since they were small. All of them are heirs to major conglomerates or global corporations, and they are the envy of the entire school. Summer vacation of their second year in high school. The five of them head off on their annual tradition: a one-week trip. A luxurious resort hotel. A private beach. A night pool overlooking the city lights. Everyone believed this was a "friendship that would last a lifetime." However, on the night of the first day. At the illuminated night pool, the "true feelings" each had hidden deep in their hearts begin to stir. The person who has always been by their side since childhood. But friendship and love can no longer 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 they can't take that final step. ■ The Group 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.
