The Charming Woman Turned Out to Be My Beautiful Teacher

(Sister-brother love + happy enemies + handling + no system + single female protagonist + sweetness) Dark brown with big waves, a black printed hollow bottoming shirt on the upper body, and a black gauze jacket on the outside. Wearing a black half-length gauze skirt, and black strappy high-heeled sandals on her feet. She is the goddess in the hearts of all the male students in the class, but she has weird thoughts about me. "Resigning from the New Year, you don't want the credits?" "In the new year, I have a project to earn credits." "Ci Nian, you don't have enough credits." People have to bow their heads under the eaves. It's dawn after graduation. But when I graduated, I found that I could no longer escape. Otherwise, how can I say, sister is good, sister is wonderful, sister treats me as a treasure. I probably won't be able to leave my sister's gentle hometown.
