In the bustling city, Zi Qiao has been looking for the girl who can make his heart beat.He believes that there is always a special person in this world who can make his heart beat faster and make him willing to sacrifice everything for him.In order to find this person, he decided to use the power of high technology, so with the help of his friend Zhanbo, he obtained a heartbeat tester.

The principle of this tester is very simple. As long as Zi Qiao comes into contact with a girl, the instrument will monitor changes in his heartbeat.If the heartbeat speed exceeds a certain threshold, it means that this girl is the one his heart is attracted to.

Zi Qiao started his experiment, dating different girls again and again.He took the tester with him and went into every appointment with high expectations, but the results were always disappointing.More than a hundred dates passed, but the heart rate tester showed no response.He began to wonder if there was something wrong with the instrument, or if his heart really stopped beating?

Just when Ziqiao felt confused, his good friend Meijia suffered an emotional blow.Her first boyfriend cheated on her again, leaving her heartbroken.Zi Qiao saw it in his eyes and felt pain in his heart.On the one hand, he comforted Meijia and told her that it was not worth being sad for such a man; on the other hand, he decided to teach that shameless bastard a lesson.

Things did not go as Ziqiao expected.When he found the man and tried to stand up for Meijia, he was beaten up by the man.Zi Qiao fell to the ground, grinning in pain, but he had no regrets because he knew he was fighting for his friends.

Afterwards, Zi Qiao took the bracelet she got back from the man and gave it back to Mei Jia.Meijia looked at the bracelet and then at the scars on Zi Qiao's face, feeling a warm current in her heart.She suddenly realized that this man who had always been by her side and was willing to stand up for her was the one she truly loved.
