Wearing the Role of a Supporting Female Character in the Era, I Got Entangled with a Yandere Boss

After transmigrating into a cannon fodder character in a period novel, Lin Xiyue returns to the city with her Educated Youth mother, only to find her maternal family unwilling to take them in due to disdain. Throwing tantrums and making a scene, Lin Xiyue orchestrates her mother’s remarriage to her first love. The mother’s first love has been a widower for years, raising a boy alone. Upon hearing the boy’s name, Lin Xiyue suddenly realizes—she has latched onto the gentle male lead’s coattails! But shouldn’t the gentle male lead be orbiting around the female protagonist? Why is he constantly clinging to her? Shouldn’t the gentle male lead have a gentle personality? Why is he so domineering, even locking her indoors? Wait, just what kind of entity is hiding inside this “gentle male lead” shell? — Lin Xiyue: Clinging to the male lead’s coattails means a blessed future ahead! Hehe~ He Mingchu: Carrying my little pet back to the nest means fun times ahead! Heehee~ — Lin Xiyue: Hold on, you’re saying this gentle male lead was replaced long ago and is actually a yandere? Can I even survive this? He Mingchu: Huh? You say I didn’t transmigrate but rather entered a book? So what? With my little pet here, survival isn’t impossible.
