- Description from novelbuddy

Twenty years ago, the Gu family’s eldest daughter, Gu Wan, went missing without any news on her whereabouts.

The Gu family was left with only the youngest daughter, Gu Chu, so they doted on her.

Twenty years later, Gu Wan returned. Gu Chu was thrilled and she showed her sister around the city, even giving her everything she treasured.

However, Gu Chu gradually realized that Gu Wan was here to take everything away from her, including her fiance! Their mother said, “We owe Gu Wan all of this. We all do, especially you! Gu Wan only went missing back then because you insisted on having a candy.

That’s why Gu Wan went out and ended up going missing!

She had suffered for twenty years out there! You will never be able to fully repay Gu Wan what you owed her!

Hence, the engagement with the Feng family should be given to Gu Wan!”

Their mother even said, “When we arranged this marriage with the Feng family, although we didn’t specify if it was for Gu Wan or Gu Chu, the elder child should take precedence.

Gu Wan should’ve been the first choice. And now that she’s back, she should take what was rightfully hers. What’s wrong with that?” Gu Chu wanted to defend herself.

She didn’t understand why Gu Wan would lie because she didn’t go missing because of her. Yet, the man chose to marry her sister, and that was when Gu Chu regained her senses.

It was just a man. Men weren’t reliable, so she didn’t want him anymore! Their mother even used their family’s shares to bribe Young Master Feng.

However, Gu Chu was surprised when the quiet and unsmiling Young Master Feng suddenly had a change of personality.

Three times a day, he would propose to her. Gu Chu asked, “Are you in such a hurry to have a wife?” Young Master Feng answered, “I’ve been planning this for a long time. Please bear with me.”

Later on, Gu Chu found out his secret. So he had actually been planning for a long time after all…

I possessed a minor character who marries the prince. I’m not thrilled about it. The prince is a scumbag who flirts with the heroine despite being engaged and eventually gets defeated by the original male lead. In the epilogue, all he does is apologize to his fiancée and marry her, with barely a line to his name. Well, his personality is twisted, but at least he’s handsome. And since he’s the third prince, he doesn’t have to shoulder the burden of ruling the kingdom. That’s decent husband material, I suppose. Go ahead, make a fool of yourself. You’re going to marry me anyway. I’ll just sit back and enjoy watching your embarrassing history unfold. “Doris Redfield. Don’t expect me to ask you to dance at this ball. Maybe not at the next one either. Or the one after that.” “Yes, Your Highness. As you wish.” “Even though we’re engaged… wait, what?” “It’s just a joke proposal our parents once tossed around, isn’t it? You don’t need to take it seriously, Your Highness. I’m really fine with it.” “…Is that so? Yes, that’s… fine, right?” Why are you panicking, prince? You started spouting nonsense first. Where’s your conscience? But then, this guy really has the audacity to ask something outrageous. “…Do you, perhaps, have another man?” The guy who flirted with the original heroine is saying this now? Calm down. He’ll regret this later. All I need to do is remain a devoted fiancée until then. “What are you talking about? A woman like me… plain, not beautiful, with a gloomy personality, what man would even—” “What? Who dared to say that about you?” …You did, in the original story. This guy is acting weird. But he’s not the only problem. “My dear little sister Doris, that dress you’re wearing today is dreadful. No wonder there are rumors His Highness has abandoned you.” “Well, it can’t be helped. His Highness is too good for me anyway.” “…Hold on. Too good? Who said that? Wait, were you really dumped?” The original villainess, who also happens to be my older sister, Natalie, is suddenly interested in my love life. Why are all the original tr*shy characters growling at each other over me now?!
