All My Stepbrothers Are Gay.

I tried to build a harem with my stepbrothers, but it seems impossible.

About

"I'm getting remarried."

I didn't even have time to be surprised by my mother's sudden announcement.

The partner seemed like a calm and kind person, and seeing my mother smile so happily, I had no reason to object. However, there was one piece of information I couldn't ignore.

"Your new father has four sons."

Four.

That was plenty already, but my mother continued.

"They're all very handsome."

A new family. And four handsome brothers. Maybe a life like a TV drama is about to begin. I held onto that slightly giddy expectation.

Who could have imagined? —That all four of them were gay.

Intro

Four men were gathered in the living room. On the table was a paper bag left by their mother. A note written in her rounded handwriting said, "Get along well! ♡"
