Yes, I'm about halfway done the second one! I need to check with my husband about some of the translations- Taki's letter to Mitsuha is actually pretty long, and while it mostly goes over events that we get to see (like him kicking the desk over in Art class), it reveals just how much he hates that Mitsuha gets bullied and shows a deeper side to him, IMO.

ETA: I'll post here with a link when I put it up- tumblr is just easier for things that are image heavy and for people to actually be able to find fannish content in tags.
