Just the other day, I got married to a man with a stepchild. My stepdaughter, Ryoko-chan, quickly accepted me, and I was living happily with my new family. Then one day, Ryoko-chan was hosting a study group with her school friends, and the boys there suddenly attacked me!! I desperately called for help from Ryoko-chan, but she just watched me being assaulted with a smile on her face. And from that day on, I began to be repeatedly assaulted by my stepdaughter's classmates...
