Rin, a carefree but absolute business-minded heir of the Ueda Group is currently going to be exiled to their newest luxury island resort before its launch as a punishment for divorcing his childhood friend, Blaise, whom he married for a business merge. This was all planned by the two so this punishment from his parents is just like a vacation for him. A week before Rin heads to his new alcove, his best friend, Ryou, asked him to take his little brother, Yuki, with him because of a new dangerous stalker. Rin was delighted to take up the offer since he had long wanted to see the adorable kid that followed him everywhere during their school days. Much to Rin’s surprise, Yuki, now 21 years old, who dresses like the main lead in dystopian sci-fi movies, is much different from the adorable and bashful kid he once knew.
