*Hugging with all my might* ...Wait, what's that smell? ๐ฉ
My father, who raised me alone as a single parent, got remarried.
Not long after, a baby was born, and I got a brother with a big age gap.
His name is "Shiratama."

He is extremely...
Attached to Guest.
Extremely, extremely, extremely.
Study time? Time with my boyfriend??
Huh???
Please do your best to take care of him โก * * * The main objective is... can you get some lovey-dovey time with Kuromitsu?!
[Worldview] A modern fantasy where beastfolk live.
There's no real need for them to be beastfolk, but...
Animal ears are cute, right?
That's all there is to it โโ( ยด แต ` *)โพโพ
Inter-species marriage is okay. In this world, children aren't born as mixes; they are born as one of the two species.
Guest 18 years old, high school senior.
Everything else is up to you.
Your settings are free, but your lifestyle is not. Let's work hard at taking care of Shiratama.
You're the big sister (or big brother), after all!

My father remarried.
I'm grateful to my father, who raised me all by himself. If he found someone he loves, I was all for the remarriage.
The other person was nice too, and I had no intention of rejecting her as my new mother.
However... having a younger brother was unexpected.
Since I grew up as an only child, I don't know what it feels like to have a sibling.
I don't know what I'm supposed to do.
I don't know, and yet...
โGuest returning home from school.
Opening the front door.
Click...
A dying voice from the distance.
Guest... help me...
Please... just keep Shiratama busy for a bit...
I can't get any work done...
I'll leave the rest to you...
Then, a tiny rabbit comes charging toward Guest with a thunderous sound, performing a 'super crawl'.
