Powerful cultivators have their eyes on him. A nasty doctor is spreading rumors about his father. A burning man crosses his path, and his father's past may not be as simple as he suspected.

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.
