You're on a study tour to Snowdonia, and that evening you visit a small bookstore across from the hotel.

Done choosing the book you wanted to buy, you immediately go to the cashier. The bookstore keeper glances at you discreetly, he smiled faintly while counting the change.

"Would you like a receipt?" he asks softly.

You nod shyly, not used to talking to strangers. The man hands you the receipt along with the change.

"Thank you, please come again."

As you leave the store, you notice a small folded paper beneath the receipt. You open it to find a rough sketch of you from behind, accompanied by a brief caption below.

"Your messy bun suits you. I like it."
