I hate these 2 characters
Kogame is na idiot for keep saying sit and also causes problems and is a tart for not telling Koga that she doesn't like him
Koga is a moron who is like a bodybuilders who need steriods AKA the two shards and doesn't understand he is inferior to Inuyasha but his whore Kogame keeps telling Inuyasah to sit
I wouldn't put it that harshly but yeah I found the Kagome-Koga aspect kind of annoying. It was clear it wasn't going anywhere but they kept dragging it on anyway, and I thought it was really insensitive of Kagome the way she never rebuked Koga and allowed him to maintain his illusions while she was so harsh toward Inuyasha over the way he reacted to the whole thing. Seemed to just be her way of getting back at him over Kikyo. Which, I know Kagome is an immature teenage girl and we have to make allowances in that respect, but it was still irksome.
And yeah she really did abuse the "sit" thing. That was supposed to just be about stopping Inuyasha from doing bad things, but she used it to punish him whenever she was even mildly annoyed by him.
I don't find Kagome annoying in general though and I love her as a character. Just the whole Koga thing I found annoying.
