Full of Charm, the Contrasting Sister Fell in Love with Me After Graduation

(No system + no rebirth + no harem + pure sweet love story + daily life + two-way running) In the eyes of others, she is crisp, mature, sexy, cool and distant, the flower of the high mountains that no one dares to approach. In your eyes, she will be jealous and lose her temper for you, act coquettishly in front of you, and say "I like you" with a blushing face. "Liqiu, do you like my black stockings?" "Liqiu, my foot is injured, please carry me." "Liqiu, why are you touching my butt, pervert... But does it feel good?" "Li Qiu, I'm not leaving tonight. I'm going to sleep at my sister's house." The iceberg melts only for you, contrasting with Sister Yu's preference, it only belongs to you who have just graduated. (The introduction cannot be one ten thousandth sweeter, the text is more fragrant)
