Wow... I went through most of that chapter thinking Subaru was a girl. When I first saw him described as a he I thought it was a typo! Obviously I read too much yuri!
I know it's just a small thing but I'm really glad that Yuuki didn't rip up that love letter, like I've seen in other manga. I think I would have been annoyed had she done that.
It hasn't been translated yet and unfortunatly I have no skills in translating, nor do I know a lot of Japanese. I'm gonna post it here in case anyone is interested in picking it up. It's a little NSFW if that helps.
Hmm, I don't really like how she got all gooey eyed over the brother at the end, though I did like how Ki-chan punished her for looking at someone else.
