Nothing to do with Ayumu's situation with 知ったことか

Grammar Explanation: Lack of interest with 知ったことか

Sakurako tells Takeru not to go to the shogi club as he’ll get in the way of Ayumu being with Urushi. However, as a new member of shogi club, and as a man, Takeru feels it’s his duty to show up.

タケル:: 「歩(あゆむ)の事情(じじょう)など知(し)ったことか」; “This has nothing to do with Ayumu's situation.”; Literal: “Is Ayumu's situation or whatever something I know?”

Key Points

1知(し)ったことか rejects concern

知(し)ったことか literally sounds like “is that something I know/care about?”
In context it means Takeru is dismissing Ayumu’s circumstances as irrelevant to his own duty.

2事情(じじょう) means circumstances or situation

歩(あゆむ)の事情(じじょう) is Ayumu’s personal situation with Urushi and the shogi club.
Takeru is not denying the situation exists; he is saying it does not matter to him.

3など adds dismissive distance

など can mean “things like” and can make the noun feel belittled or brushed aside.
That nuance fits Takeru’s exaggeratedly serious resolve to go anyway.
