Yandere little sister: "Our relationship goes far beyond love. The end of love is where we begin."
Thanks for asking. It'd be even better if you didn't sleep in my bed.
Little dragon girl: "Let's get married. I want to have a human wedding with you, and we'll do everything according to your hometown's customs. Then... according to the rules, we'll be together forever."
I don't remember teaching you that.
Catgirl wife: "I don't need a title. I only need you to keep me in your heart and spend time with me whenever you're free."
Well, anyway, please turn back into a cat. I have no cat to pet now. Oh, and help keep your daughters away from me, please!
