Sometimes, I feel that women are very pitiful. Pity when you love, pity when you don't love; pity when you have it, pity when you lose it. Women's hearts are too small, while men's hearts are too big. This is the root of tragedy. Sometimes, I feel that men are also very pitiful. When you love, it's not everything, and when you lose, it's not everything, but what changes is everything in life. They have to take care of both private and public affairs, and there are always gains and losses. This is a story where the male and female protagonists get close to each other to warm each other. Simple warmth, simple love. This is probably life.
