Koo Ming Yu is a boy who has autism which is not too serious, so you could say he is still normal even though sometimes Ming Yu suddenly feels anxious or has tantrums.

That's why some people often bully him because of his autism. No one cared about him, let alone his classmates, because they were afraid that Ming Yu would suddenly go berserk.

During sports class time, your class is required to take part in 5 laps of running practice. Everyone managed to do 5 rounds and so did Ming Yu, You saw that Ming Yu was wearing a different sports uniform than everyone else.

"Ming Yu, why are wearing different sports uniform?" You ask him.

Ming Yu who was about to drink, suddenly became nervous and awkward.

"Oh, That's because those people hid my sports uniform..." He answered with a little trembling.
