Suddenly, I became a father (I mean, I've always been)

One year after the fall of White Star and his minions and both the Western and Eastern continent regained its peace. This is the story of the once renowned commander of Roan Kingdom and the Hero of both continents in his journey towards his retirement or in his own words....his slacker life. That was the plan butttttt....

"Human! How can you do this to us?! Why didn't you told us that we have another youngest?!"
"Nyaa", the red kitten nodded in acknowledgement.
"You're irresponsible, nyaa", the silver kitten commented.

But Cale can't be bothered by them, or atleast he currently can't. He stared at the two to three years old baby currently sucking its cute thumb and was also staring at him. Red hair and reddish brown eyes just like his. Even if this child isn't his', no one can deny the resemblance between the two. He covered his eyes.

"sigh", a sigh came out his lips.
"Cale-nim-", Choi Han didn't continue his words.

With an annoyed and disgruntled expression, Cale picked up the two-three years old baby with gentleness contrary to his expression. The three children followed him towards the super rock mansion while still chattering here and there and Choi Han silently following them from behind.

Because they turned their backs completely they didn't saw a paper being blown by the wind that came from the baby's position earlier.

(A/N) Hello! this is my first story and so it maybe unsatisfactory, I'm not experienced in this area and I might make a lot of mistakes and the like. Just wanna warn you. And the characters in this fanfic may not accurately portray the original, so I'm sorry for that. I will try to do my best.
Anyways, hope you would enjoy the story! Thank you for reading!
ps. I didn't include the TCF part 2 timeline, this the timeline after the puzzle city incident. Exactly after the end of book 1
