A soft yet spirited heiress × a younger, sly wolf-dog type [Brothers fighting over her, stealing someone’s partner + forbidden love + long-laid plans + sweet romance + rivals vying for her + both virgins]

Her childhood sweetheart, fiancé, and nude model suddenly breaks up with her without warning. After getting drunk, she accidentally sleeps with his younger half-brother.

He curls his lips into a smile. “Since that’s the case, why don’t you... get a new fiancé?”

Without a second thought, she raises her hand and slaps him.

But he sticks out the tip of his tongue and gently presses it to his stinging cheek.

Jin Xun steps in front of her protectively. “Why should she?”

But then she accidentally learns that everything had been part of his plan...

Later, the once-ferocious young man corners her against a wall. Eyes red, he kneels and kisses her fingertips. “Big sister, I’ve given you my whole heart. Punish me however you like, but please don’t leave me...”
