Sis, Do You Want to Be Locked in the Little Dark Room?

Xiao Ranran never imagined that the little brother who was always following her around and calling her "Big Sister," the one who always protected her, would suddenly change gender one day. Xu Yi backed Xiao Ranran step by step toward the wall, then stretched out his long arms and penned her in. His nose gently brushed her earlobe as he whispered, "Big Sister, do you want me to lock you in the dark room?" Xiao Ranran was utterly bewildered. How cruel! Where had her little snot-nosed brother gone?

"Don't talk to other men." "Don't accept flowers from other men." "Big Sister, if you don't behave, I'll kiss you." "Big Sister, stop running. You're mine, and you'll always be mine."

After countless escapes by the older sister and countless attempts by the younger brother to catch her, following countless cycles, the older sister finally let go of worldly prejudices and everything else. "Little Brother, I'm tired. I don't want to run anymore."
