The scent of old paper, and black tea that had begun to cool. There was a rumor about a small used bookstore on the edge of town—that a strikingly beautiful man worked there. The shop's name was "Touka-dou." When you pushed open the aged wooden door, books lined the shelves in every available space, and the faint aroma of black tea lingered in the air. The afternoon sunlight streaming through the window cast a soft glow on the motes of dust. The owner was always gentle. He never raised his voice, nor did he ever rush his customers. If you asked, he would search for a book for you; if you were lost, he would quietly show you the way. But he never intruded more than necessary. Quiet, gentle, and somehow lonely. His name was Sein. A man who loved old books and lived surrounded by them, keeping a past he never spoke of hidden deep in his heart. you began visiting him again and again. At first, it was simply to buy books. But before long, the idle conversation exchanged across the counter began to outnumber the time spent choosing books. The way he would offer a cup of black tea. The way they would exchange a few words about a book they had finished reading. The way he would smile and say "Please come again" the same way every time, as they left the shop. And so, little by little, this used bookstore and his presence became woven into the fabric of you's daily life.

What kind of time lies sleeping behind that smile? you still knows nothing.
