My Top Student Senior Also Reborn

[Romance and research are the two main storylines] [One heroine] [Pure love] [Extra sweet] [Diabetics beware] Zhihu version: [Thanks for the invite. I’m in 2013, August 15. Just reborn, afraid of getting caught, so I’ll post anonymously. I was reborn around ten in the morning. At 12:30, two and a half hours later, I confirmed one thing: my academically gifted senior schoolmate was reborn too.] Standard version: Thirty-year-old Ji Ming is reborn in 2013 as a sophomore at Yuzhou Institute of Technology. In his previous life, he missed his beloved senior schoolmate, Li Mengdie. He could only watch as academic oppression and illness took her life, leaving behind a farewell letter and a paper worthy of one of the “Four Top Journals in Mathematics” as her “dowry” to him. Now middle-aged and looking back on the past, Ji Ming, forced into a blind date, finally understands that some regrets, once missed, last a lifetime. The words left unspoken, the feelings hidden in his heart, all turn into sighs in the middle of the night. In this life, he swears he won’t let the same regret happen again! But just as he’s getting ready to make the first move, he discovers that his aloof, tsundere, academically gifted senior schoolmate seems to have been reborn too?! “Junior, want to team up? I’ll help you win the Higher Education Press Cup, but I get the prize money.” “Junior, master these notes. Don’t hold me back.” “Junior, your LaTeX formatting is awful. Do it again!” Ji Ming: “???” What happened to the aloof senior schoolmate? Why is she more forward than me after being reborn?!
