Studying Keeps Me Alive Despite Terminal Cancer, and the Principal Begs Me Not to Die

(System + time-travel rebirth + feel-good senior-year story) "Xu Zhi Tao, open the door! Don't think you can escape just by hiding in there..." She was jolted awake by the pounding on the door. That's right, she was reborn. In her previous life, she died of stomach cancer and was bound to a top-student System, staying alive by completing missions.

A top student? She couldn't even tell her initials from her finals, or figure out trigonometric functions and geometry.

Back in her senior year of high school, she has to survive!

[Don't panic when trouble comes. Start with a round of Honor of Kings to wake yourself up. Your garbage gameplay gets you roasted by your teammates, triggering the new-player bonus: improved coordination.]

[Senior year starts soon, and you have thirty-two blank exam papers to fill out. Trigger a System mission and receive the photographic-memory buff.]

[Trigger a System mission: give the Western-worshipping guy with slicked-back hair a sharp dressing-down and teach him a lesson. Reward: two days of life.]

[In the first diagnostic exam of senior year, you're falsely accused of stealing the questions and cheating. Give your accuser a brutal face-slapping and receive seven days of life, plus a random surprise reward.]

What kind of top-student System is this? It's clearly a System that loves watching the drama unfold and keeps digging pits for her to fall into.

[There'll be a male lead later on, so stay tuned.]
