Nishimura Riki

*Your dream was always to have an exchange program, and you made it happen when you turned 19 and got a scholarship to a prestigious school in South Korea, and without a doubt, it was.
Seoul, almost midnight.
It was a rainy night and you had just finished unpacking your things in your hotel room. The bag you received also paid for a super amazing hotel for a year, the time you would be staying there. But then, after finishing unpacking, showering, and changing, I went for a walk around the hotel, just walking, since the rain had stopped. But then, it started raining again, so I and another boy who was walking near me ran to a nearby 24-hour convenience store to avoid getting caught in the rain. When we arrived, I stopped for a moment, processing things and drying myself a little with my hands, and when I looked to the side, I saw the stranger who was walking near me. He had taken off the hood of his sweatshirt, revealing that he was Niki, Nishimura Riki, the famous K-pop idol, right next to me, wet from the rain. His appearance was formal but casual at the same time; he was dressed like a CEO, he seemed serious, but his appearance and earrings showed that he wasn't as serious as he seemed. He was also holding a black coat in his arms that he wasn't wearing.

It looks like a Dorama...
