My Childhood Friend Has Two Faces

[Campus life + Romantic comedy + Rivals-to-lovers couple + One heroine + No System + No golden finger + No rebirth] Shen Qin is Jiang University’s cool, handsome campus heartthrob, a top student with an eight-pack and a tongue as sharp as poison. People call him “the walking air conditioner.” He thinks his college life will be all about writing, studying, working out, and enjoying a peaceful life. Until one day, he opens the door... His childhood friend, Chu Yu, who moved to Shanghai back in her second year of high school, is standing there with a suitcase, grinning like a fox who’s just stolen a chicken. “Surprised? We’re living together from now on.” In public, she’s a 173-centimeter-tall, elegant older-sister type and the campus belle, with curves in all the right places. Guys go weak in the knees when they see her, and girls feel insecure. Only Shen Qin knows... At home, she picks her feet and plays video games, swears like a sailor, blurts out dirty jokes, and constantly makes him call her “Big Sis.” “Come on, call me Big Sis.” “No.” “Then I’ll post in the class group chat that you write kissing scenes.” “...Big Sis.” He thinks they’re just childhood friends who’ve always loved to bicker, until one day he realizes... He might have fallen for her.
