[when asked if he understands, Killua nods once. his steps still when Blue's do.

he watches Blue, heart twisting. partially because he feels for him, and partially because he feels bad. but the truth is that he can't relate. he probably hasn't even had enough close relationships outside of his own family to run into such trouble.]

...Mm, I haven't.

But I understand things being more complicated than people seem willing to accept. I didn't realize... but I know that's annoying.

[apologizing again is pointless; Blue will either accept it or he won't. all Killua can do now is listen, and accept the bed he's made.]
