Hello!
Fun story - I actually translated this drama way back when it first aired and then was much too lazy to do the timing for it when a very nice person amh1988 over at livejournal posted up pre-timed files over at Sub Sub Gakkou.
Which means I can now provide softsubs to you!
RULES: ...None. My name doesn't even appear on the subs. If you
are going to re-translate or hardsub though, just give me a heads up
^_^.
Credits for timing go to amh1988@LJ who I'm also told moderates Ao no Michi (the subbing community). They'll also be uploading hardsubs of the drama (with my translations), so if you prefer that I'll provide a link to those as well when they pop up.
The videos I used to time the file are from Nyaa torrents, but I think it's the same video file located in other places as well.

By the way I really recommend this drama. It's super cute slice-of-life that touches on LGBTQ topics in one of the best ways - by just encouraging open-mindedness and the mindblowing concept that gay people are just.... regular people???!! WHAT.
But no, seriously, it's lovely. It revolves around Yaichi, his daughter Kana, and Mike, the husband to Yaichi's late brother Ryoji. It's super cute because it shows Kana's complete openness to Mike being gay which is adorable and really runs home the fact that children really don't care about sexual orientation - they're taught to discriminate, but if you just present being gay to them as something that just is, it won't be a big deal! It also deals with Yaichi who is an adult and has clearly struggled with the idea of his twin brother being gay, and how he slowly comes to accept and realize that it doesn't make a different either - that Ryoji was and will always have been his brother, and Mike is now his brother-in-law and that they're a family, gay uncle or not. The supporting cast and how they react to Mike is also really great.
It's just such a nice and heartwarming way to give representation. Check it out!
