The "apartment comedy with laughs and tears" centers on a 4-year-old boy named Kotarō Satо̄, who moves next door to Shin Karino, an unsuccessful manga artist. Kotarō has no parents and lives alone. Not only does he seem to earn a living, he actually seems more put together than his own strange neighbors.
