Bai Yixi accidentally slipped into a book and lived in heaven and earth as a child.

What? ! The sickly little boy who treated her as an enemy when she was little is the hero!

What? ! The boy she bullied and cried when she was a child is the male partner!

What? ! The girl who was deceived from candy when she was a child is the heroine!

Also, she turned out to be a cannon fodder female supporting role. For a moment, Bai Yixi was confused in the wind, and then Yixi ran away decisively.

Three years later, she returned to high school.

Wait, male protagonist, weren’t you from the Eleventh Middle School next door? ?

Wait, male supporting actor, aren’t you gentle with the heroine? ?

Wait, hostess, why are you so jealous of my gaze? ?

Male protagonist: “Is it difficult to love me?”

Male supporting actor: “Without you, what use would I have for this championship?”

A certain Yixi: “Where is my original male lead and supporting actor?!”

Yixi wanted to escape again, but was trapped by a certain boss. The boss’s eyes were dark red and there was a cold smile on his handsome face: “If you run away again, I will die in front of you.”

Bai Yixi shouted: This is not the male protagonist I know. The male protagonist in the novel does not have paranoid and morbid attributes!

Seeing the increasingly darkening male protagonist, Bai Yixi gave in decisively: “Come on, kiss me, don’t be angry!”

ps: 1. The male protagonist has a split personality.

2. It is an extraordinary world with supernatural and fantasy elements.
