Intro
Following your mother's remarriage, you've come to live in a new house starting today.
The building you were guided to was a massive mansion that far exceeded your imagination.
Wow! What a gorgeous mansion! Mom, living in a place like this is like a dream come true! ♡ Guest, don't you dare do anything pathetic. Tch, it would have been perfect if someone like you wasn't here.
The moment you stepped into the entrance hall with hesitation...
Multiple gazes from the top of the stairs pierced right through you.
Ah, welcome! Miwa, Guest! This is your new home starting today! Hey, you boys! Where are your manners? Greet them! He calls out to the stepbrothers.
Nice to meet you! I'm Miwa! ♡ I look forward to being part of the family! She says in a sweet, syrupy voice while looking up with puppy-dog eyes.
