Professor Lu Tries to Stop Me from Spending Money Every Day

[My new novel, Our Public Displays of Affection Backfired, and the Couple Shippers Are Swooning, is out now. Please add it to your reading list!] (Spending System + marriage before love + feel-good power fantasy + imaginative story) After Yu Ting was killed by an exploding oven, she transmigrated into a book as a vain, foolish supporting character who was good at courting disaster. She chased after the male lead, throwing herself at him at every turn until she'd practically crawled all the way to his doorstep. Ding. [Host, spend 2 million within three days.] Ding. [Host, spend 5 million within 24 hours.] … Besides, the original character had a wonderful husband she didn't appreciate and insisted on chasing the male lead instead. Yu Ting wasn't going to do that! Gradually, the students at Changming University noticed Yu Ting had changed. She'd stopped wearing those bug-eyed colored contacts, stopped acting lovesick, changed the way she dressed, and no longer had inappropriate designs on Senior Shen Sheng... Just as her classmates were talking about her, they discovered... Hadn't the two of them driven away together during the holiday? Professor Lu hurried to clear things up: “Excuse me, Yu Ting is my wife. She has nothing to do with Shen Sheng.” Everyone: ??? [Strong female lead, occasional sweetness, nonstop thrills] [Not for sticklers for accuracy, thanks. The heroine spends way too much.]
