One is a firefighter who saves people from danger; the other is a doctor whose mission is to save lives and heal the injured. They attended the same high school and later enrolled at the same university. Back in high school, the moment Qi Bo'an first saw Jasmine, he recognized her as the girl he'd met when he was little. At first, he simply kept an eye on her from afar, but gradually his attention turned into affection. Whenever people asked what his ideal type was, Qi Bo'an described Jasmine: cheerful, brave, and with a heart-shaped smile. By the time they graduated from university, he had planned to confess his feelings. But then he saw a young man standing close beside Jasmine, the two of them looking intimate as she smiled sweetly. So Qi Bo'an buried his feelings deep in his heart. Later, while carrying out a mission, he never expected to run into Jasmine. He had thought three years would be enough to get over her completely, but the moment he saw her, his heart still raced against his will.
Jasmine was born into a family that favored boys over girls, but fortunately, she had a grandmother who doted on her. Sadly, fate had other plans: her grandmother passed away while Jasmine was at university. One blow after another sent Jasmine into a low point in her life. During that time, she often received a letter and a little teddy bear. The encouraging words in the letters shone like a light, and they exchanged letters for nearly half a year. Then the replies stopped. Later, Jasmine met a mentor and a senior student, and her life finally got back on track. One day, after rescuing someone, Jasmine passed by the scene of an incident and met Qi Bo'an, who was there as a firefighter. And so their story began.
