PleaseTwins, while light-hearted, also bases its plot on a fair amount of ecchi. This potential naughtiness, while purely entertaining for its intended Japanese audience, may clash a little more harshly with American taboos. It involves a boy named Maiku Kamishiro who has a picture of himself standing in front of his house as a child with a little girl who is his cousin. Now in high school, Maiku's family is too disparate for him to know exactly who that little girl grew into: he only knows it is one of his two best friends, Karen and Miina. Both girls are in love with Maiku and in the classic indecisive style of love-triangle anime, Maiku is in love with both of them. This creates an issue of potentially incestuous feelings, though Maiku doesn't know which girl he longs for crosses the boundary. This creates the fundamental predicament of the show: all three characters want to discover which girl is in the picture but are simultaneously afraid of what the discovery will mean for their lives. ~ Cammila Albertson, All Movie Guide
