I adore these lyrics lol. As someone who's chronically shy I totally relate. Just the way you want to say things, but you're too nervous, then you say something you didn't mean or when you finally get things out they sound odd. Kikka plays up the character of these lyrics brilliantly as well.
I've listened to this song a few times now so I must like it. I didn't expect to based on the preview since the last song I really got into from Kikkawa was "URAHARA Temptation", which seems to be nearly the opposite to this.
I liked her Wildflower/Urahara type stuff a lot, but I also REALLY like this new direction her music has gone this single. It's exactly the type of J-pop I was into in High School and I still really enjoy listening to it.
