บท 427: Chapter 427 Good Brothers

Zhou Siyu arrived at school early in the morning, and she had an extra trick up her sleeve. When it was almost time for the exam, she took the opportunity to use the restroom, purposely passing by Shen Mianmian's exam room entrance on the way.

Seeing Shen Mianmian sitting inside in high spirits, Zhou Siyu immediately ground her teeth in anger.

Just from her complexion, Shen Mianmian must have had a good day yesterday.

Last night, they had waited until it was dark and the school was closed before going home, and this morning, both uncle and aunt had intercepted her halfway, yet that damn girl still managed to run to school.

Did she tunnel her way out from underground?

It was infuriating.

"Zhou Siyu, what are you doing standing here? Aren't you going to your classroom to prepare for the exam?" On his way back from the restroom to his office, the principal saw Zhou Siyu standing at the door looking inside. His expression changed, and he scolded her with dissatisfaction.
