Hin, Fei and Yin have been each others' best friends since young. Hin n Fei are high jumpers and they work really hard on the training. Unfortunately, Hin once got injured before an important match. It made him feel despair about the future. Yin tried to cheer him up, so she decided to practice high jump. She wanted to let Hin know that she and Fei will hold him tight and never let go of him as they have promised each other. Hin is now rejuvenated and blessed with Fai and Yin’s efforts in encouraging him.
