She's the Female Supporting Character in a Pure-Love Story

Blurb:

Reborn inside a boys' love novel as an unremarkable passerby girl.

After she accidentally helps the protagonist bottom a few times, the beautiful young man grabs her wrist and says through gritted teeth, "Fifth Miss Ji, you're getting married? So why did you lead me on?"

Ji Mengze's head is about to explode. She tries to break free. "Are you crazy? Let go."

Lian Nu stares at her, resentment filling his heart. He hates her hypocritical air of innocence after she stirred up his feelings and then acted as if nothing had happened. "You'll pay for this."

The male lead, a top, hides his identity and takes refuge in her residence.

After she exposes him, he appears gentle, but presses her relentlessly with questions. "Fifth Miss Ji, did you really say in front of everyone that you fell in love with me at first sight and couldn't stop thinking about me?"

Ji Mengze forces a smile. "I was talking nonsense. Don't take it seriously."

"Fifth Miss Ji, but you're already my fiancée." He had never understood love. She had been captivated by his looks and flirted with him in every way, only to beat a hasty retreat when she discovered his true identity, hoping to pretend none of it had ever happened.

How could he let that happen?

Naturally, the lowborn young man would seize his chance and take his revenge, then marry her into his household and show her firsthand what happens when you toy with someone's heart and refuse to take responsibility.

PS: The protagonists are in a straight romance. They're both straight.

Theme: Live this one life in the way you choose.
