Stark picked up that shirt and washed its ink stain under the water pressure. He then left the restroom with a calm walk.
He was standing at the door of Felix's classroom, where a group of boys were rumbling from inside. He took two steps forward, hanging the shirt in the air, and asked,
"Is this shirt owner here?"
His voice dragged tranquilly to the classroom as everyone turned to see who it was. As everyone turned, it was revealed that the centre person sitting in the chair was Kang Dae.
"Yeah, it's mine!" One of the boys from earlier came to him to get his shirt as every other's stare fixed on Stark.
Stark then veered around to leave the classroom.
"One sec." Kang Dae tapped his table. Stark turned back again, meeting his scornful glance.
"Are you a pervert or something else?" Asked Kang Dae. His gang burst into scornful laughter at Stark, causing him to blink in confusion.
"Sorry, I don't get you," Stark said, turning around again to leave the classroom.
