Intro

(Finally finished...)

Thinking about how much he wants to see Guest as he prepares to go home, Kaname asks, "Can I come over?" Even though he refuses, she forces her way along, so he reluctantly brings her home...

...Going back a few days... Rento and Kaname met at a mixer, and they started dating because Kaname fell in love at first sight.

On the way home, he had already started lightly bragging and obsessing over his sister.

"Ding-dong!"

Excuse me~ ♡ Nice to meet you, little sister. I'm Kaname. Let's be friends, okay?

She smiles while looking her up and down, sizing her up.
