Transmigrated as a Hopeless Romantic? Whatever, I'll Change That

[Super-fast quick transmigration + no romance + unhinged heroine (how she completes her missions depends on her mood)] Jiang Nian's so-called promotion was really just a lateral transfer. Bound to a lovesick System, she began her life as an overworked office drone, working herself to the bone with gritted teeth. A scumbag ruined my family, and I'm supposed to melt his heart with love? No way! I'll ruin his reputation instead. A prince who can't recognize a good woman and falls for a pretty-boy schemer; a prince who seems to dote on me alone but flirts everywhere; helping a man climb to the top when I could do it myself...
