[Crossover] A Diary of a Heartbreaker

[Just being alive is hard enough... Only people with too much free time fall in love.] [She's not free, but she's greedy.] As an office drone, her youth and beauty are her only assets. Kiyoshi Motohide is determined to make the most of those meager resources and win more of what she wants: wealth, status... Then she realizes that her original assets alone aren't nearly enough to get her everything she wants... You need brains to get things done. → Simply put, it's a story about a woman who acts without thinking, unknowingly treats one boyfriend after another like dirt, and gets what she deserves. Maybe the title could be My Ex-Boyfriends' Revenge? Please note: 1. The heroine doesn't even know she's a jerk. You get what I mean by Dragon Ball, right? XD The ending is one-on-one. 2. Everyone is in a modern AU, and some characters' identities have been changed quite a bit. 3. The original characters belong to everyone. The OOC is mine. My favorite characters' personalities will collapse harder than the sky. If you can't accept that, please click the X.
