My Keychain

Tin is an ordinary student walking home from school. One day, he encounters Na, a student from another school. Na was running away from his bullies when he accidentally bumped into Tin. After the two schoolboys crossed paths, the keychains in their backpacks got tangled together. Reluctantly, Na forfeited his bag to the stranger he had just met. They make arrangements to meet up again once their schoolbags are separated.
