In spite of this setback, he and his teacher gradually get to know each other and a romance blossoms between them. However, soon enough, the principal of the school finds out about their relationship. The solution? Get married!

Together, the newlyweds must keep their marriage a secret, not only from Kei's high school friends, but also the Galaxy Federation. Onegai☆Teacher is the fragile but comedic love story of an alien and her student.

Onegai☆Twins
Maiku Kamishiro's past has always been somewhat of a mystery to him. The only clue he has to who his family might be is an old photograph showing two young children, a boy and a girl, playing in a small pool outside of a blue house. In an attempt to find his family, he moves to this blue house and begins working as a programmer. He's living a comfortable life until the day two very different girls show up at his door, both in possession of the same photograph, and both claiming to be his twin. With no way to prove who is a relative and who is a stranger, Maiku allows both girls to move in with him until they know for sure.
