The Sealed Answer Sheet

At Jingling No. 1 High School, everyone in the senior class knows two things: Shen Zhiyan, the top student, is aloof and proper, while Lu Che, forever in second place, is rebellious and hard to tame.

They are stepsisters in name only, classmates who spend every day together, and lovers hiding in plain sight.

Shen Zhiyan is the student council president everyone respects. She's always been disciplined and reserved, but she repeatedly makes exceptions for Lu Che. Outside school, Lu Che is the leader of a group of devoted followers, afraid of nothing, yet she willingly lets Shen Zhiyan keep her in line.

Rumors quietly spread through the grade, and malicious gossip comes rushing at them. Lu Che can't stand people smearing Shen Zhiyan and dares to call them out in public. Shen Zhiyan is used to restraining herself and enduring in silence, but at night, when no one is around, she secretly plans birthday surprises for Lu Che.

On the night of Lu Che's eighteenth birthday, the boundaries they've maintained for so long finally dissolve, and the feelings they've kept suppressed can no longer be held back.

They face the suspicion and criticism of others, hide the traces of their embraces, and support each other through their senior year, buried in exam papers and countdowns.

They don't need to explain themselves to anyone or expect everyone to understand.

After weathering the endless sea of practice questions and exam preparations, once the college entrance exam is over and they seal their answer sheets, they won't have to hide anymore.

Theme: In the pressure of youth, young people rely on each other, face rumors, stay true to themselves, and grow together through companionship.
