I, Extra, Steal the Trash-Eating Male Lead

Modern corporate slave Lin Xin transmigrates as an extra in a campus novel and accidentally unlocks the bullet comment function, discovering that the fallen youth Tang Zhou is the future richest man. She decisively rescues and shelters Tang Zhou, helping him return to school and escape his abusive mother. Through daily companionship, both fall for each other, ignoring the original female lead (who is also a transmigrator). Together, they break the plot constraints, confirm their feelings, and jointly control their own lives.
