Similar in the sense that it's a slow married life sort of scenario, with a heroine who lacks any traditional sex appeal, eliminating the ability of the author to over-sexualize her too much.
Boku no Tsuma is, however, very different in many other aspects, especially if the concept of human-like AI frightens you (as it does me).
