Lin Cheng, a girl who transferred to an urban high school from out of town, walked into a completely unfamiliar world with a little loneliness and timidity. She never relied on others and was used to solving all problems by herself until she met Gu Yan, a sunny and cheerful boy who always brought her warmth and peace of mind.
Gu Yan is a popular figure in the school, with excellent grades and great popularity. However, he has never been aloof. Instead, he always cares about everyone around him with a warm and tolerant attitude. He was not indifferent to Lin Cheng, the newly transferred girl, but instead took the initiative to extend a hand of friendship. In her world, he became the brightest light, leading her out of the shadow of loneliness.
As time went by, the relationship between the two gradually warmed up. Lin Cheng gradually became dependent on Gu Yan's company from being initially defensive, and Gu Yan also quietly realized that his feelings for Lin Cheng were no longer as simple as friendship.
