I Snatched Bai Yueguang at the Beginning, and She Turned Black

[Non-single female protagonist + scheming + treacherous + not a virgin + decisive killing] Yun Lie traveled through an urban novel where spiritual energy was revived, and became the most incompetent but most favored youngest son of the villain family. The 'arrogant and domineering villain' system was bound to the system on the day of time travel. Bai Yueguang, who has been engaged since childhood, wants to break off the engagement? What's the point of losing face if you just call it quits? Just bring a bunch of losers to snatch the bride! I originally thought that the heroine Bai Yueguang would hate me to the core. I never expected that the heroine Bai Yueguang's painting style would gradually become weird. "Yunlie lied to me to surprise me." "Yunlie had no choice but to marry the Princess of the Wind Clan." "Yun Lie is extremely talented and has a noble status. It is inevitable that he will attract jealousy and hatred. As his fiancée, we must share weal and woe." "I will hit whoever Yun Lie hits!" Except for the heroine Bai Yueguang, all the other heroines in the original work will gradually turn darker as long as they come into contact with Yun Lie. Yunlie was also very helpless about this. Just telling white lies. Why are all the heroines turned black?
