After class, Sang Yu left the classroom looking deflated.
Bal and Hei Sen chased after her, "Sang Yu, what's wrong? You look like you've lost your soul."
"I really have lost my soul." Sang Yu blinked her innocent big eyes at the dark-skinned Hei Sen, "Did you take notes?"
Hei Sen grinned and said, "Wow, the sun has risen from the west. You're actually asking to borrow my notes?"
"Not borrowing, forget it!" Sang Yu snorted and ran downstairs hugging her books.
Bal kicked Hei Sen and shouted downstairs, "Sang Yu, you can have mine."
"Toss it down." Sang Yu looked up toward the upper floor.
"I'll bring it down for you." Bal quickly walked down, "What's wrong? Did something happen? You didn't even go eat lunch."
"Let me tell you, I helped someone big time, and they treated me to lunch. Next time, if I have such good luck, I'll bring you and Hei Sen along."
