In her previous life, Lan Lan realized her dream and got married to her best friend Gu Qiyun. Gu Qiyun met all the criteria for a boss, except for one thing: he didn't love her. Everyone said that they were a perfect match, but she was the only one who knew that this marriage was a silent despair. In this life, Lan Lan was reborn and returned to college. She was full of joy and planned to start a new life, but she still couldn't escape the arrangement of fate. Gu Qiyun turned into a brother three years younger than her! The parents of both families unanimously asked her, a college fish, to tutor Gu Qiyun in his high school studies. Lan Lan thought that she was a farmer who had become a singing star, and that she could vent out the grievances she had suffered on this younger brother. Unexpectedly, even in front of Gu Qiyun, who was three years younger, she was still as timid as a dog. Lan Lan: Please give me some face and listen to this chapter. You have an exam tomorrow, right? ? ? Gu Qiyun (after five minutes of silence): Oh, the teacher said I am exempt from the exam. Lan Lan: This... That's it... Okay, sister, let's go first and see you later...(He hurriedly picked up his bag and got up, but was thrown to the bed) Gu Qiyun lowered his voice and bit Lan Lan's ear: It's hard for my sister to teach me, so I'll teach her this time. Lan Lan (shocked): Teach... What? ? Gu Qiyun chuckled: Teach my sister how to like me. Lan Lan:? ? ? ! ! ! The little wolfdog from Bingshan High School x the cowardly college student is cured by being sweet.
