I mean, it's shoujo and so it's going to have these issues, but I found the two leads to have all the raging sexual chemistry that you expect to find from a relationship between Tinkerbell and Spock - that is, none whatsoever. The male lead, Uehara, is undemonstrative and withholding right to the edge of abuse, and the female protagonist, Nao, is romantically deluded and simple right to the edge of stupidity. Nao receives love confessions from several other boys who would all be better matches for her, but, no, the leads are trapped in a universe where they are destined to be together. The lead actors are both charismatic and deft given what they have to work with, but what really saves and redeems the show are the secondary and tertiary characters who are all quite likable and winning. There are a couple truly affecting moments in the series, and it is ultimately worth watching for those moments.
