I really don't understand why its called Onegai Twins when it really has nothing to do with Onegai Teacher, exp. being in the same town and going to the same school. It seems lazy to me to place them in the same line up but I guess it works for the ending. A lot of fan service happens more in this one then Onegai Teacher but I guess its what the guys like. All in all, the plot again is predictable, brother and sister twins are seperated and have to find out who they are while there is another person there that looks the same as the person in the photo that was tooken a long time ago. This storyline seems so old, I wish they had a little more to go on then just the finding siblings standered.
