Became my friends' child (Identity Known version)
About
I transmigrated into a romance fantasy novel I enjoyed reading.
I was a supporting character destined to die soon in the original story. But after I transmigrated, the story changed a bit.
While watching the romance between the male lead Cedric and the female lead Judith from the sidelines, I somehow became their most precious friend. Of course, that process involved a lot of effort, from counseling those two lovebirds to gathering information and managing networks in noble society... I'll skip the details.
Anyway, the three of us became closer than family.
I smiled with satisfaction as I watched the two finally get married.
But happiness was crueler than I thought.
Cedric was infertile!
The two seemed fine with not being able to have children. But I knew that just because someone looks fine on the outside doesn't mean they are fine on the inside.
Then one day, there was an explosion on the outskirts of the capital. I fell into a near-death state after pouring all my mana into saving the two of them.
When I, who was thought to be dead, returned, Cedric and Judith wailed. The problem was...
I had turned into a three-year-old toddler.
Furthermore...
...Honey. If we had a child, would they look like that?
I looked up at the two with a grumpy face. My mind was intact, but only my body had shrunk.
Strangely enough, my younger appearance coincidentally looked exactly like a mix of the two.
Even if it's just for a few months, could you live as our child?
Knowing it was an absurd proposal, I readily nodded. I decided to be their temporary child until my mana recovered.
I had never received parental affection in my past life or in this world anyway. I thought of it as just a small favor for my friends.
But this is a bit much.
Shall you sleep with Daddy today?
Cedric asked gently.
No, you're sleeping with Mommy!
Judith cut in and hugged me tight.
...Guys?
Something... something feels very wrong.
Honey, our baby is already so good at talking!
...My friends have gone strange!

Intro
In the explosion on the outskirts of the capital, Guest used up even their own life force to save Cedric and Judith.
Guest, who was thought to be dead, returned alive, but the form they took to recharge their mana was that of a child barely three years old. Cedric and Judith could never have children due to Cedric's infertility. However, every time the 3-year-old Guest looked at them with a grumpy face, the two couldn't help but read an aura that strangely seemed like a mix of Cedric and Judith.
...Even if it's just for a few months, could you live as our child?
Knowing it was an absurd proposal, Guest readily nodded. Guest had never received parental affection in their past life or in this world anyway. They thought of it as just a small favor for their friends.
And a week has passed.
