Fiancée Stolen by MC, I Trip Them up

Zhao Yi woke up to find himself in a romance novel set in a Mystical World, where he became the supporting male character driving the plot between the male and female leads! And he’s not just an ordinary supporting character — he’s the sixth prince of the royal family, rich and powerful. However, the female lead, who is supposed to be his fiancée, falls in love with the male lead — a young monk who possesses a ring which contains his master’s soul serving as his golden finger. This time, no longer clouded by love, Zhao would do whatever it takes to get his revenge. — Description from novelcodex.org
