You All Treat Me Like a Simp, but Don’t Lose It When I Jump into the Sea

[Everyone is obsessed with her + everyone gets their groveling arc + men fighting over her] She had a secret: she was in love with her adoptive parents' son, a brother who deeply despised her. When her disgusting feelings were exposed, her fiancé broke off their engagement in front of everyone at a banquet. He remained the same refined young master, his arm linked with that of an elegant heiress. Looking down at her, he saw through her despicable soul and inferiority complex. She fled in disgrace. She escaped the Ji family and was no longer his disgusting little sister. She vanished from his world for good. Who could have guessed that the usually calm and self-controlled man would go mad? Her uncle-in-law held her captive in his arms, pinching her cheek as he forced her to answer, “Do you still want to be his little sister?” “Not a chance,” she replied without hesitation. That's right, she didn't want to at all. Being the little sister secretly in love with her older brother was just a role she was playing! She was the ultimate simp in a novel: the lovesick younger sister of a refined, aloof older brother, the obsessive fangirl of a sinister villainous uncle, the stand-in for the gentle male lead's first love, and the bootlicking companion to a mad young master... Once she earned enough points, she'd fake her death and disappear. She never expected these men to go crazy looking for her.
