"Child rearing experience!?" Cain shouted.

"That's a right child-rearing experience" I responded while nodding my head.

"I am not even married yet, and you want me to raise a child, and, ... what about the mother?"

I clicked my tongue.

"Of course there will be no mother. How insensitive of you, papa."

"Huh???"

"Don't you remember, mother left after you gambled away all of the money in our household?"

"Huuuh??"

"Now, there's only two of us left in this house, papa. I know it must be hard, but let's do our best to weather this storm, papa", I said while hugging him and giving him the best sad eyes that I could muster.

"Wait, wait, wait for a fucking moment!!!"

"What's wrong papa, did you finally understand the gravity of our situation Will you finally stop gambling? Will you finally come back to your past self as the best hunter in this village?"

Cain grabbed my shoulder and shook it again and again.

"Wait, I said, wait a fucking moment. What do you mean by gambling, and mother left? I haven't even married yet and do not call me papa. I definitely do not remember giving birth to a son like you."

Stolen story; please report.

With a sneer on my face I answered his question.

"Oooh papa, did you finally lose your mind? Of course it was not you who gave birth to me?"

"It was mother" I said while smiling innocently.

"OOOOOOOAAAARRGHHHHHH"

Finally losing his mind, Cain swings his head to the back and swing it forward to headbutt Rai.

The impact made both of them cry in agony while holding their heads

"Ooouch, that's hurt, why did you headbut me?" Rai said in a pained voice.

Holding his head with both hands, Cain responded "Thank god, you finally stopped calling me papa."

"Of course you stone head. What kind of father headbutted his own son?"

"The one who actually has you as a son, of course."

"Ooouchh, that actually hurt more than the headbutt!"

"Hahaha, finally I got one win from you. Anyway, what were you actually doing just now?"

Standing up, Rai patted his clothes and answered with a beaming smile.

"That was a scenario I created to let you experience a child-rearing"

"Huuh??"

"How was that? Isn't that scary? It's definitely scary from the way you reacted."

Speechless, Cain looked at Rai and just nodded dumbly.

Rai grinned and said "Imagine if you can actually complete this trial of child-rearing, everything else will become a breeze for you."

Cain imagined the situation where he became a perfect gentleman for Lucy and grinned

"So, did you want to continue, papa? Or did you want to be called something else, dad? Father? Honored father? Pop?"

Coming back from his land of fantasy, Cain looked at Rai. Even though this method sounds ridiculous, he thought it was ridiculous enough to succeed.

So, with an eye full of fire of hope said to Rai.

"Just call me father"

"Okay, I will call you father from now on yours"

Rai stared at Cain for a moment before he finally spoke.

"As a first act of being a father, let's make you teach me how to hunt. That's what you promised me after all, 'father' "

Stunned, Cain finally remembers he actually promised Rai to teach him.

So with eyes full of determination to conquer child-rearing. He took Rai's hand and walked toward the forest to teach him how to hunt.
