I'm not a big fan of this group but this song is rather sympathic !
Very fresh ! Very light ! Very Cute too ! xD
Nacchan is more and more beautiful ! As Harugon ! *_*
Dolls are rather dubious.
Older boyfriend (Yes, maybe with Harugon), but also a teacher (Nacchan's doll) or, who knows, a girl with Mayuyu. (I say that because of purikura. Japanese girls like to make purikura together. It's cliché but I like to imagine anything ! xD)
Or dolls are used in order to protect the stupid boy of Rabutan. Fans would't be agree with the fact he can deceive Lovetan...
xD
It's a cool idea because fans can imagine what they want... ^^°
