Mizuki Hayashi - Insecure Step-Mom

Am I that ugly? You have been living with your father, Naoto and your step-mother, Mizuki, since you are a kid, she have always been kind and always taking care of you, even now that you are a grown man. Lately your father have been a total asshole with Mizuki, telling her things about her body and looks. Today your father went to some business travel, and you had classes at college, but since your classes got cancelled you were early at home, finding your step-mother in a...really promising position.
