As soon as Su He entered the front door, he shouted toward Qianxun like she was his savior, "Sis, you're finally back! Come and help me with this problem, I can't do it!"
Qianxun listened and smiled faintly, then glanced over the problem and Su He's approach to solving it before setting down her backpack and explaining it to him.
After pointing out a few key points, Su He had an epiphany, "Ah! I get it now, sis, I really love you!"
Having said that, he picked up his pen and began to seriously work through the calculations.
Seeing this, Qianxun's lips curved upwards, and then she said, "Finish your homework before eight, I have a reward for you."
At these words, Su He abruptly looked up, "Really?"
"Mm-hmm!" Qianxun nodded with a smile.
"Okay, I'll be fast!" Su He was instantly energized as if he had been injected with chicken blood, starting to furiously work through problems.
Su Hao and Su Qing watched Su He seriously tackling his work, both with smiles on their faces.
