Perhaps it's because he thought that it's okay. Il-tak himself was 'forced' to sit on his lap and has no choice, might be the reason why the *red head (sorry for the mistake) audacious of touching him all over. Misinterpretation sometimes, about boys acting all gay. I have a group of friends, mostly boys are clingy to each other but not to the point that it will grope and act touch starved like that.
Some people found this type of manhwa disgusting. Yes, it is but we all know that we are perverts, and this type of manhwa... If we put down our common sense that il-tak is experiencing continues sexual harassment from the orange head and twisted adoration from her little sister, we can all say that the story is actually funny....
