My Beautiful Sister-In-Law Who Changed and My Childhood Friend Who Just Made Her High School Debut Barged Into My House?

When I met my sister-in-law again for the first time in several years, she was so beautiful that I couldn’t help but be surprised.

“Nice to meet you again, brother.”

“Ah…”

She used to be a crybaby and was withdrawn, often following me around and being a spoiled child.

Now she’s a pretty curt but cool looking girl. Therefore, rather than being my younger sister, she feels like someone of the same age and a member of the opposite s*x, thus I felt nervous about living together again.

“Um, you said you wanted to ride on my back like old times… but isn’t this a little too close?”

“? It was always like this.”

In spite of that, she still treats me like how she used to, and I can’t measure the distance between us.

Even after growing up, there are some things that didn’t change.

My childhood friend was neither reserved, nor did she care. She would enter my room as if she owned the place, but it was natural for her to be right next to me.

She was closer to me than anyone else, even more than family, and I grew up with her as if we were actual siblings.

“Oh, erot*c doujinshi! What is this about?”

“Oh, that’s the one that was propagated. Well, if you read it, you’ll understand.”

Just before she entered high school, she had transformed into a beautiful girl who could be mistaken for a supermodel.

“Look! This is the perfect and ideal high school debut!”

“No, it’s a scam!”

She’s a cheeky yet bubbly girl, and if she continues to treat me like how she used to, she will cause trouble both at home and at school.

This is the story of my younger sister who has transformed into a completely different person, and my childhood friend who is my closest family, and how we began living under one roof.
