On March 31, 2023, the short story "Thanks to the Broken Engagement, I Got a Fiancée" won an award at Micro Magazine GC Novels' [GCN Bunko 1st Anniversary Short Story Award].

There were many who testified that his fiancée, a ducal daughter, had bullied the Saintess.

It was a situation where even a false accusation could be made to stick.

That is, if it weren't for a certain boy.

His name is Serfil, a reincarnator of an old man who got drunk, dunked his head in a toilet, and drowned.

To protect his family's ducal house, Serfil works hard!

Oh, the world's strongest cross-dressing female margrave has become his fiancée?!

Ugh, I don't need this kind of trouble!

The broken engagement is not the main focus.

From then on, the story of the impish Serfil begins.

This is the serialized version.

[The Third Son of the Hyburg Family is an Impish Shota, Vol. 1-2] have been released.

A manga adaptation has been greenlit.
