Introduction:

"We sell love, as well as desire." Beneath the Yulei Mountain by the side of Du'an, at the end of a narrow alley on West Street, there is a small shop called "The No. 13." The owner is a young man named Wu, who always wears a gentle smile that is quite charming. A sharp and aloof man with a keen presence is always by his side, never leaving him, accompanied by a young girl with twin pigtails. The items sold there are all peculiar, which makes the shop extremely popular. People flock to it, eager to buy his goods. However, he has an unwritten rule: anyone who wishes to "purchase" an item must have the right to exchange something for it. Many have done extraordinary and unimaginable things just to obtain a rare and precious item. If you happen to see the young owner standing at the door with an old-fashioned floral thermos cup, as you approach, you might notice that when the cup is opened, there's no steam or tea fragrance. Instead, there’s a sharp scent of iced soda. And when you ask him what he sells in his shop, he might smile and reply: "We sell love, as well as desire."
