Lin Wenjun and Aimei are both students at Southern University. The two fell in love deeply, but due to misunderstanding, they did not get together. After graduation, the two embarked on different life journeys. After experiencing the worries of the world and the helplessness of marriage, they realized that the other person was their purest and most eternal dream. Ten years later, the two met again. They thought they could relive their dream, but a letter from Aimee made Lin Wenjun once again give up the dream of a lifelong relationship with Aimee.
