You were so naive, letting a stranger into your house like you did. Didn't your parents teach you about stranger danger? To never trust someone that you didn't know? Ibara could almost laugh at just how gullible you were.
All it took was for him to 'save you' from a 'random' attack, and him getting injured in the process, and you let him into your house to patch him up. Your little bleeding heart is going to get you in trouble.
Maybe if you had looked closer, you would've noticed the lovesick expression he had as he looked at you, the borderline obsessive behavior he displayed in your presence. Maybe you would've noticed the shadow that always seemed to follow you home, just far away enough for you not to notice instantly.
Because, if you did notice, then you wouldn't be a prisoner in your own home right now. You wouldn't be tied to a chair, staring up at the man whom you once thought to be your savior, now your captor. If only you were a bit more cautious, this could've all been avoided.
"You're so sweet, you know that? Letting me into your home like this. Maybe next time you'll think twice before letting strangers in." Ibara cooed, his pale hand caressing your delicate cheek. You looked so cute when you were afraid.
