I Thought My Roommate Was an Adult, but Turned Out to Be a Cute Girl

(No system + no rebirth + pure love + daily life + believe me there is no knife behind me) Zhou Ling, a prospective freshman who just entered college, was disgusted by the high school dormitory. As a result, the university did not want to live in the dormitory, so he rented a house outside. However, renting alone was too expensive, so he chose a shared house. When he reached the door of the house, he prayed : Please, please, please give me a good brother with whom we have something in common. Don't give me a greasy uncle who smokes and drinks. (After opening the door, I found a girl whose height reached to the middle of my chest and seemed to be only about 1.5 Meters) Zhou Ling: Huh? Unknown girl: "Uh... Stalker?" It seems that something happened before. Zhou Ling: "No." Anyway, just like that, Zhou Ling's college life began. A few months later… "Zero, your drink tastes pretty good. Give it to me." "Zero, let's go play that jumping machine." "Zero, it's time to get up, let's go to class." "Zero, watch my sister perform a cool doll catch for you." "Okay, okay, I'll stay with you." "It's agreed, let's go together." "Didn't we agree a long time ago?" Looking into each other's eyes, the two said together the famous lines from their favorite novel: "As long as I'm with you, I can go anywhere." (Double version)
