Fumihiko Matsumaru is a 26-year-old salaryman for a snack company, who got stood up at the movie theater. Just as he was about to throw the tickets away, a passing girl asked him to take her into the movie instead. It turns out that she is an aspiring seiyuu named Aka Onda. Later, when her home burns down, he lets her share his apartment, and eventually she gets hired to do the voice for a character in a commercial he designed.

I've only read 5 volumes of this so far (there are 8, but only 5 translated, and no official American release) but it is pretty entertaining so far. The art is simplistic but attractive and clean; the characters are interesting and the plot moves along at a nice pace. It's a very cute, romantic story, and is occasionally also quite funny. (Caution: It often gets pretty sexual in nature, and it's kind of fanservicey besides. It's not porn, but it goes about as far as non-ero manga can go in that regard.)

There's an anime series, too (I just started watching it) but it's very short - only 9 episodes, 15 minutes each. The anime is a fair bit toned down from the questionable content of the comic, if that matters to you.
