After Being in the Drama, I Was Chased by My Childhood Sweetheart.

One-sentence synopsis: A brother and sister live a warm life, but in the name of family, they 'bully' their younger sister. Shen Gu traveled through time and was bound to the doting sister system. Shen Gu, who had no sister, was bound to the lively and cute Xiao Qingmei downstairs, and from then on he embarked on the path of upgrading his 'pet' sister. "Sister, it doesn't matter if you have poor grades. If you can't find a job in the future, I will leave all the leftovers from my brother's house to you." "Sister, it seems that the innermost tooth of yours has a cavity." The younger sister was so frightened that she opened her mouth unpreparedly, and a paper ball flew into her mouth like a basketball. Shen Gu was laughing next to her. "Sister, give me a bite of the ice cream for my brother." After taking a sip, my sister held the empty box and cried without tears. "Brother, why do you always bully me?" "My sister is not being bullied, it would be meaningless." "Come here, take my brother away~" … This novel and its characters are purely fictitious.
