This is the heartbreaking moment a schoolgirl confesses her feelings for her teenage crush by giving him a bunch of balloons - only to be cruelly rejected.

College student Nguyen Thi Nguyet, 17, had spent months infatuated with the classmate and decided to reveal how she felt about him in Hanoi, Vietnam.

She chose the country’s Women’s Day - the equivalent of Valentine’s Day - where men give gifts to women but she bravely switched the roles.

Nguyen bought half a dozen brightly coloured balloons tied together and after classes she nervously approached her teenage crush.

With hundreds of pupils watching all expecting a happy ending, she calmly walked over to ask him for a date.

But the lad was stony-faced and despite others pushing him back to her he angrily knocked the balloons to the ground amidst the sound of gasps from pupils.

Humiliated Nguyen was left in floods of tears as her friends rushed to comfort her outside the Hanoi University of Industry.

Onlooker Do Thai Thu, 17, said: ‘I went to the school to see a friend and saw what was happening and started to film it. A lot of people were watching but there was an unexpected ending. It was a surprise. I thought they would walk away together. It was not nice for the boy to do this to the girl. He could have been a lot nicer because everybody was watching, he should have thought about her feelings.'

The incident divided opinion in Vietnam with some criticising the boy for ''humiliating'' the girl while others defended him, saying he had no responsibility to be her boyfriend.
