Lee, a young man in Chengdu China, writes a letter to Sam, his former English teacher and lover from the US, reminiscing about their brief but profound relationship. He recalls their time together through past and present moments—exploring the city, learning from each other, and falling in love. But Sam had to return to the U.S., leaving Lee with cherished yet painful memories. "Tenderness" is a poetic tale of love, loss, and the lingering warmth of a connection that remains unforgettable.
