Candy Boy - Trailer
Who says imouto (sister) love needs to be straight? Technically, Candy Boy isn't an imouto, because the sisters are actually twins, but they're gay. There's not much of a plot aside from the two sisters being very close in a Yuri way, and the clingy underclassman who always annoys them for falling in love with one of the sisters. However, this is one of those melodramas where there's teasing and you just want to tap the screen and pop their heads together for them to actually kiss.
