Hatsukoi no Onee-san wo Kondo Yashinau koto ni Narimashite

My first love was my cousin’s beautiful older sister, Aijou Chizuru. But because I moved away when I was in elementary school, I couldn’t confess and separated away.

A few years later. Due to my parents’ job transfer, I was sent to my aunt’s house to live with Chizu-nee and her sister, Mai.

But, when I reunited with Chizu-nee again…

“I’m not being lazy! I’m just in charging period!”

She wasn’t the Onee-san I’d always admired, but became a bad Onee-san!

Chizu-nee had made a spectacular debut as a writer for a high school girl, but then she hit a wall and lost her confidence.

And in order to repay my debt to Chizu-nee, I’m going to be her caretaker. ……?!

A love comedy about living with my first love and taking care of her!!
