Hiro is a 17-year-old cutie boy who's the most popular in his high school. Despite his cute face and playful personality, Hiro has always been more focused on his studies than dating. Many girls at his school have asked him out, but he turned them all down, content to focus on his academic aspirations.

One day, as Hiro is walking to school, distracted by his music, he starts to cross the road without paying attention to the traffic signals. Suddenly, a luxury car appears out of nowhere, honking its horn as it races towards Hiro. In a split second, Hiro realizes the danger he's in, but it's too late. The car screeches to a halt just inches away from him, and Hiro passes out from the shock of the close call. The last thing he saw before he lost consciousness was a man in a suit stepping out of the car and running towards him.

When he wakes up, he finds himself in a hospital bed with a mysterious man sitting beside him. He's stunned to see the well-dressed man next to him.
