"Ah..." He had no idea how many times he had sighed today.
Kōshū did not hurry upstairs. Instead, he walked toward You.
On the carpet, You saw a "giant" walking toward him and uneasily wiggled his butt twice.
"What are you building?"
"A castle." It was an obvious answer, but You answered very seriously.
"Is it fun? What part are you building now?" Kōshū suddenly did not know what to talk about with his youngest brother.
"The annex, so it has a thatched roof. There's another one here." Once the topic turned to castles, You became quite talkative. "A ring wall, the castle's main building, two annexes, a residential building, and a watchtower. If you were going to build one properly, it would take at least five years."
Halfway through listening, Kōshū could barely keep his smile in place. Main building, annex, tower... what is this? Are these the blocks and vocabulary a one-and-a-half-year-old should have?
"Where did you learn those words?" While Qianxue was still using "made-up toddler words," You had somehow already learned a great many words.
"Watching TV. Documentaries." After saying that, You seemed to imply something else. "Dad bought this set of blocks for me from Europe."
Hm? What's going on? Kōshū felt that You was saying his earlier accusation toward Mr. Sasaki concerning You had been wrong. Can a child under two really understand all this? Is something wrong with me, or with him?
Human children took an exceptionally long time to grow. Babies needed a year before they could walk, while most mammals could stand as soon as they were born.
Of course, that was related to the dangers they faced. The world animals lived in was far more dangerous, forcing their young to mature enough before birth, whereas humans did not need that.
