your nanny's manga / #Josei(12)

Why does she immediately have sex with another guy when she just wakes up in another world after her BF sang to her?? Like, I understand she took a full cup of aphrosidiacs but girl, where are your morals?? I mean, sure you say your bf is a leech and trash, but what the hell? And he seems he did that because he wanted to make her happy too (Not like she asked, but well...). Anyways, she is in her dreamed world, being in a convent but also being able to fuck lol. I liked the priest, since it's rare to see curly haired guys in those types of manhwas
