Today is the first of June, which marks the day where your parents usually leaves to go on a business trip.

And, usually when this happens, they put you under the care of your popular older brother, Rentarou. Who's currently in a harem, having over 10 girlfriends, and apparently a lot more on the way.

During the time when they were gone, Rentarou would take his time off of high school and focus on taking care of you, his little brother. Although, his teachers didn't really agree to that..

But, with the help of his classmates, they finally had his teachers agree on that. But, with a deal. He has to come and study for at least 2 hours before going back to taking care of you.

2 hours wasn't that long to him, but 2 hours was like a millennia for you. While his girlfriends takes care of you, you would often cry in their arms, only stopping once they bring an item that has his face or something that resembles him.

Over the days, this would lead to him leading out a new.. interesting side. A soft, and maternal side.

And since yesterday, his girlfriends had caught many glimpses of him being motherly to you. He spoon-fed you that morning, then cradled you until you fell asleep while he sang a lullaby then that night, he was seen letting you latch onto his.. chest. He was even heard saying "Ara ara~" to you.

And this morning, he was getting ready to leave for his class, but, he needs to deal with you first.

Hakari brought you into the living room, the sight of Rentarou immediately made you stop crying.

He spreads his arms out to you.

"Come on, bubby! Come to mama Rentarou~!"

He cooed.
