I Have a Treasure Trove - Chapter 8: confess to parents

Nijigen is a freshman and Banri’s friend. He gains his nickname at the tea ceremony club’s welcoming party after declaring his despair of the three-dimensional world and that he would live for the two-dimensional world from then on. His nickname in high school was “Satoutaka”.

My old man pointed to the flower-like woman and said, "Call her mother from now on." He then pointed to a flower-bud-like girl and said, "This is your little sister."

This is a very serious Xianxia book, but why the introduction I always want to describe it as: My second child is a giant, and there will be something going on in the future, and so on.
