At 23, Shi Hua suddenly unlocked her family's inherited succubus System. After unlocking three character slots for high-quality men, it seemed she had no choice but to enter a romance story where readers bet on their favorite love interest.
A gentle, well-behaved younger man (as an adult, a professor with a silver tongue and a heart of stone) / A gloomy, Japanese-style company president and notorious playboy (with mild self-destructive tendencies and an inclination toward abstinence) / Her best business partner, the wealthiest ship merchant (a man whose lips couldn't be pried open even with a gun to his head, now transformed into a machine for sweet nothings).
The descriptions before the parentheses are what they were like before meeting Shi Hua; the descriptions in parentheses are what they're like after falling in love with her.
Faced with this situation, Shi Hua touched her pretty little face and cheered herself on. She could still handle this!
Theme: Adults should take responsibility for their own love lives.
