After Being Rejected by Senior Sisters, My Demoness Master Actually Gave Herself to Me

What?! I'll die if I don't date?! I confessed to seven senior sisters, and none of them said yes! I'm going to turn around and force my demonic master to leave this hellhole. But, Master, are you crazy? Why did you agree to date me? I really didn't want to date you! And senior sisters, you're all abnormal! You didn't agree when I confessed, so why are you all clinging to me now? Senior sisters, fairies, saintesses, princesses… please be more reserved, my master will get jealous!
