Song Zhengguo, having eaten and drunk his fill, now resembled a head teacher. He sat down beside Zhao Xinlan and gestured for Zhou Siyu to join them.
"Siyu, come sit here, and I'll go over the problems with you."
Zhou Siyu didn't want to sit too close to him, but having invested so much, she finally had what she desired and couldn't miss out.
So, suppressing her revulsion, she sat on the other side of Song Zhengguo, who revealed a sly smile and, with an arm around each of them, began to go over the problems, occasionally leaning in to kiss them on the ear.
After about forty minutes, the sky outside slowly darkened, and Song Zhengguo reluctantly let them go.
"I'll stay up late tonight to list out the problems I've worked out. Try to come as early as possible tomorrow, and I guarantee you'll be able to get into high school."
"Mm."
Zhou Siyu and Zhao Xinlan echoed a response and then finally left together.
