What Do I Do About All These Sisters-in-Law?

After my older brother was supposedly killed in battle while leading an expedition, I, his fake replacement who had been disguised as a man, inherited his beautiful harem. I began arranging for them to fake their deaths so they could reunite with their true loves, sending them off to convents to rekindle old romances, and marrying them off to other men as secondary wives.

I was delighted to play matchmaker and dismiss my brother's harem, convinced no one in the world was better at shipping couples than me. That is, until one day, my supposedly dead brother came back.

I started to panic and pack my things, planning to flee the capital under cover of night on my little red horse.

But my brother yanked me off the horse and carried me straight to the imperial bed, saying, "Trying to run?"

"Too late."

"I had three thousand beauties in my harem. You can make it up to me all by yourself."

Me: ...

This is absurd, but the imperial bed really is soft and comfortable.

One-on-one, both leads are virgins, no blood relation, a sweet little story. The blurb is in first person, the main text in third person.
