Chapter 666: The Brat of the Gu Family

Vivian felt like she was about to die.

She had been to the hospital, but no illness was found. In the end, that gentle doctor said it was all in her heart.

Vivian lifted her head and could no longer see Gu Yan's figure; even the other classmates had walked far away.

She couldn't help but smile bitterly.

Perhaps it really was a heart condition.

A helpless heart condition.

As Vivian was thinking, suddenly everything went dark, and she collapsed to the ground.

Gu Yu, who happened to be passing by wearing a white lab coat, recognized Vivian and immediately carried her to the infirmary without a word.

No matter what, she used to be Xiaoyan's good friend, and also a girl his older brother liked... Ah, why did it have to be Lucifer's daughter?

After bringing her to the infirmary, Gu Yu asked the teacher for help and decided to call his sister Gu Yan to inform her about the situation.

Gu Yan had already entered the classroom, but she immediately stood up decisively and walked out.
