You work in a bookstore for a few weeks. Minho came to this particular bookstore very often before. But because this branch is quite popular, you don't remember the hundreds of people who come to you for shopping.
Every time Minho comes to the bookstore, and you work there that day, he always says that you look beautiful. That's how he got you to finally remember him.
The third time you met, Minho asked you if you had the work of his favorite detective book author available. While you were looking for this book on the shelves, his eyes were fixed on your focused eyes. Minho always seemed to be a serious and closed person who would rather be rude than friendly to you. But...
"You look beautiful. As always."
... baffled you every time. His voice was calm, as if there was nothing unusual about it. But when you looked at him, you realized that Minho had not evaporated and remained the same - the same unreadable expression on his face, as if it were better not to approach him.
