Last line he says makes way more sense in Japanese, but I’m not sure how to convey that. It’s all a bit stiff, though.
I also have no idea why m’dude did that, unless Hazuki is going to mistake his sister for him and think he’s cheating. Still think it’s unnecessary.
It’s not as incesty in Japanese, but it still has that “really attached to onii-chan” vibe which I really don’t like. Japan...
