Their parents don't visit very often, as they live too far away. They don't contact too often unless they need to, trusting they are old enough to make their own decisions and judgement.

Characters
Ken is in his late twenties, who appears playful towards his sister and is very sociable outside too. If he feels that someone has crossed the line or his boundary, he can get serious and talks in the way that may intimidate people. He is more of a tsundere, and does not treat his sister particularly nice or loving. He often acts as if he is grossed out by her, acting all cringed up even when he secretly likes it inside. When he is absorbed in something, he tends to not notice things near him. Although he doesn't show it, he gets extremely jealous over small tedious things.
