How Could the Boy I Raised Be the Insectoid Queen?

Recommendation:

I found a boy and raised him as my little brother. I never expected that after she turned into a woman, she would stare right at me and say, "You smell so good. I want to eat you..." "...Mmm, I can't bear to."

Caught by that jaw-dropping title? Come take a look!

Synopsis:

After transmigrating to a forbidden land in another world, I found a frail boy in a pile of bones.

He couldn't speak, but he followed me everywhere. I raised him as my little brother, but there was something strange about him.

Lesser monsters cowered at the sight of him, and even the old shaman of the orc tribe told me he wasn't human.

I didn't believe the shaman until the night the boy vanished. Suddenly, a gorgeous girl pinned me to the bed.

Her fangs pressed against my neck, her slit pupils filled with obsession. "You smell so good. I want to eat every last bit of you..."

A more serious synopsis

Buren transmigrated into a Western fantasy world as a berserker. His predecessor was murdered by the mercenary captain, who also stole his family's heirloom ring.

He found a child on the frontier and unexpectedly ended up allied with the orcs.

The female leader of the antelope tribe wanted him to stay, and the old white fox duke wanted him as his son-in-law...

One day, he suddenly discovered that the boy he'd found had turned into a woman, her eyes full of infatuation with him.

So, does that make him the man of the Zerg Queen now?

Wait, why does the Queen want to eat him?! What do you mean eating one's husband is a Zerg tradition?!

To make matters worse, the Sun God has assigned Buren the fate of a hero, but given him none of a hero's abilities.

The gods' schemes, the ring's secrets, the orcs' destiny, the upheaval of the three realms...

What will become of it all?
