I Got My Possession Stolen!

[Possession Project Initiated] Suddenly, I find myself possessed by Baek Seo-han in the high-intensity, dark BL novel 'Never Ending,' thanks to a mysterious system. But wait, I'm a sub-character who torments the main character, Lee Do-hoon, and gets killed? [Warning! Synchronization rate is extremely low. The body may act unpredictably.] To make matters worse, the previous 'Baek Seo-han' occasionally takes over my body. To survive, I must destroy the slave contract with Lee Do-hoon and raise my synchronization rate by doing good deeds, which is so unlike 'Baek Seo-han'... Yet, strangely, every time I do something, handsome men keep flocking to me. "Are you scared of me? Why? I haven't done anything scary yet." "You lock me up here and then go out and play with Jin Yeon-oh, is that fun?" "Ugh... I didn't mean to, sniff, but can't you be nice to me too...?" 'Why is everyone around me insane?'
