Just took a break from AV and watch Nisekoi. I think I'll keep on watching it. Funny though, I don't mean to make a dirty comment, but it's funny that the guy holds the lock while the girl has the key. Okay, enough of that.
The OP theme song does favor Chitogi, but it shows the other characters. For ED song in Nisekoi, it spotlights Chitoge again. It's better than Golden Time's OP and ED which only shows Koko.
I actually hope he goes with Onodera. It's always the odd girl in the love triangle series. For harem, it's always the first girl, not your childhood friend.
