Rewatching "Kyoshiro to Towa no Sora", though it's partially because I suspect it turn wrong at some point and I may as well just mark it as not rewatchable.
Currently watching Kono Aozora ni Yakusoku Wo. Yikes, that protagonist is so old, I've seen plenty of (somewhat realistic compared to shotas that exist too) grandfathers of main characters that would look the same.
