Lin Yu, a designer born in rural areas, walks alone in the city with low self-esteem and sensitivity. He was used to self-denial, always secretly wiping tears of frustration when he was alone, especially when facing a bright girl like Su Xiao, he would instinctively retreat - she was a city girl who grew up in the sun, cheerful and warm, and was used to conveying kindness through actions, but she was always too nervous to notice his delicate mood swings.
A pack of tissues in the stairwell, a cup of hot milk tea on overtime night, a word of encouragement when changing the plan... Su Xiao's kindness is like a glimmer of light, shining into Lin Yu's closed world little by little, but it also often causes misunderstandings due to his over-interpretation: he will be secretly sad because she is joking with the opposite sex, will deliberately alienate because of the gap in family background, and even build a high wall with inferiority to push people away when she takes the initiative to approach.
From the heart-pounding test when they first met, to the accumulation of misunderstandings and the drifting apart, to the outbreak of conflicts due to family changes and work challenges, they saw each other's sincerity clearly in collisions. Lin Yu finally understood that true love has nothing to do with family background and background; Su Xiao also understood that companionship and understanding are the best way to resolve inferiority complex.
This is a story about the growth and redemption of ordinary people - a boy who is sensitive and has low self-esteem will eventually learn to be confident in love, and a bright and warm girl will learn to be tolerant in company. When the glimmer of light on the island gathers into a river of stars, they will eventually join hands to turn ordinary days into the warmest life.
