A brave confession in high school resulted in Lin Wanxing's "inappropriateness" and became Gao Mingqing's unfinished regret in his youth. After graduating from normal school, he returned to the county high school to teach. However, when he was leading the first graduating class, he was heartbroken by Han Ruoyu, a student who had just turned nineteen - "Gao Mingqing, I like you. You must agree to be with me after the college entrance examination!"
The fiery confession broke the boundary between teacher and student, and the peach-eyed girl's persistence and purity illuminated his ordinary life like the blazing sun in midsummer. There are countless coquettish words hidden in the video calls of long-distance relationships, and the sweetness of "I love you" three times a day is beyond the limit. Side-by-side on the high-speed train, cuddling in the B&B, and walking side-by-side on campus turn simple companionship into the sweetest candy.
But behind the sweetness, hidden dangers gradually emerge: Han's father's strong opposition and blind date arrangement, President Jiang's persistent pursuit, and Lin Wanxing's unexpected reappearance due to work cooperation are all quietly testing this love that transcends age and status.
This is a two-way journey of pure love and sweet love, and it is also a period of staying together that becomes more and more determined in the test of reality. When the gentle Chinese teacher meets the blazing little sun, past regrets finally become a prologue. Only each other's sincerity can withstand all wind and rain, and let the sweetness brought by the summer wind spread into the warmth of the rest of life.
Intention: pure love
