18 years old student propose to his teacher in schhol and was rejected

A teenage boy declared his love for his school teacher and was obviously rejected by the stunned teacher in cringe worthy scenes.
The boy, who is believed to be around 17 or 18 years old, even had some of his friends help him out, but the public stunt did not go as planned.
He had a bright red banner declaring: "Miss Li, I love you! Marry me" which was unveiled as the teacher, named Miss Li arrived on campus as the Chinese secondary school.
As more and more pupils came out to watch, the boy stood holding a bouquet of flowers.
Next to him stood one of his friends who was playing what looked like a small guitar or a ukulele, with his voice belting out from an amplifier on the ground nearby.
The friend sang Teresa Teng’s classic love song "The Moon Portrays My Heart" and the brave boy got on one knee to confess his love for her, followed by the marriage proposal.
In the now viral video of the incident, the teacher can be heard saying: "Stop, stop fooling around. Please get up," while she tries to stand him stand back up.
But the boy continues to hold the bouquet and refuses to give up.
The teacher, growing impatient, shouts back: "I have a boyfriend."

Hearing this, the young suitor only becomes more hopeful and pulls a ring from his pocket and presents it to his teacher.
But the teacher loses her temper, throws the flowers at him, throws the instrument to the ground and kicks over the amp.
Before storming off she could be heard saying: "I have a boyfriend. I told you to stop fooling around. I told you I have a boyfriend."
It is unclear what the pupil or teacher decided to do next.
