This is so typical it’s scary.
We have a bunch of bishoujo girl types here, like a childhood friend-type (1st pic), then a fallen-angel type (2nd-3rd pic), then a nosy cousin, a shy flower-lover, a small sensei (ala Sensei no Ojikan), and a sensei doctor. Have I forgotten anyone else? They are so forgettable. Anyway do we have a plot? At least we have some kind of conspiracy about the male lead himself. It’s a quite simple story about the side-effects of time travel, but since the rest of the series seems so ‘normal’ adding up this little sci-fi at the end doesn’t really match. In any case, this is typical bishoujo anime. Not bad, not too good either.
