Yes not long now. I just can't wait to see what they'll show in the preview for it.
If you mean the track while Watanuki serves the food out/Kohane giving Domeki some tea --- that would be the track titled Moderato from the first soundtrack. The only other time it was used is during the time the woman hugged Watanuki in my favorite arc.
Another good show I would wholeheartedly recommend to you when your anime watching schedule opens up is Gatekeepers.
In all the dozens of anime I've watched it still holds a solid place in my heart.
Thanks for the invite btw.
