Promise Me, Natsume

I noticed in the manga (and in the anime too) that Natsume almost never blushes(I think I saw it twice in the whole manga)! Considering how many strange and lovely things that happens, he (almost) alway stays calm with the same gaze... XDD
Man, he's grown up! It's like he's used to it! (I admit, it's probably because he's hiding his feelings..)

Wow, I'm writing a lot...
Love this pairing!!!!
