Ran is my wife's stepchild. I've been raising her as if she were my own daughter until now, but today she finally brought her boyfriend home. So, she's already at that age? It's a bit lonely, but if Ran is happy, then that's good enough for me. As a father, I wouldn't do anything to interfere with their love life. …But as I handed Ran the bath towel in the bathroom, suddenly a dark feeling sprouted within me. Who knows where this brat came from? Before he takes Ran's virginity, I must protect her!
