The quintessential teacher/student relationship manga. ^^ If you like that kind of shoujo story, then this is perfect manga for you.

The story is more interesting I think in that they're actually married from the start, and it's a marriage of necessity that seems to grow into love. Still a chaste love, though - when will they kiss?! But their relationship is adorable and engaging nonetheless. Fumino's not the typical shoujo girl in that she has a lot more spunk and can take care of herself. Her little brother Teppei is just adorable! And Sensei himself is at the same time the romantic lead and the comic relief. Love it.

It's about evenly split between a dramatic sort of love and comedic, fluffy moments, but both are equally amazing. The art is nice, not the best I've ever seen, but very straightforward and functional for this manga.

Basically, it's a fun series to read. You'll get invested in the characters, you'll laugh, you'll anxiously await the next chapter. The perfect shoujo manga.
