He is a firefighter, his face blackened by smoke, coming from the flames, and in one glance, his life was set.The first time he met the young girl, she bent slightly towards him and said, “Sir...”He was amused, thinking she was a little eccentric...She had never seen such a handsome man, tall like a general, and when their eyes met, she was bewildered and forgot she wasn't in the palace...Later, during the school art performance, the young girl sat on stage, dressed in ancient costume, with a veil covering her face, holding a pipa, her eyebrows shy, appearing both delicate and graceful...He raised his alluring eyes, recalling the girl said she knew a little about musical instruments and chess; she was modest.Seeing him in the audience, her heart raced, wanting to perform well but accidentally struck the wrong chord, fortunately unnoticed by him...Later still, the young girl, now grown, suddenly confessed to him, and the usually calm and composed man was caught off guard...It was a love she had hidden deep in her heart for many years, like shards of glass in her palm, both a patient endurance and impulsive agony...The joy of love at first sight, a hidden affection...She would never know that the brother she secretly admired had been waiting for her to grow up...

Everyone knew Shen Nianshen so well.
In this world, there would probably be no female creatures that could enter his heart. Even the most beautiful girl in the school was coldly rejected.

Until one day, when there was a basketball match at the school. In the front row of the audience, there was a girl whose head was accidentally hit by the ball.

Shen Nianshen immediately ran to her. Everybody thought that he only went to get the ball. Unexpectedly, he squatted down in front of the girl, stroked her head gently, and asked anxiously, “Does it hurt?”

This a sweet love story between a cold guy and a lively girl.
