was released on November 24, 2004. The title is いえないコトバ. It is pronounced 'Ienai Kotoba' and can be translated as 'The Words I Can't Say'. There is no c/w.
This single was released a week after her previous single. The song is a ballad and has the distinction of being Aiko's third-longest recording (5:32). The song was featured as the ending song of the anime 'Samurai Gun'.
The PV puts Aiko at the end of a once-promising relationship with a guy who wears a flannel shirt. We only see the guy from behind; Aiko stares up at him from a park bench at a gorgeous seaside location. He turns and walks away from her. She goes back to her hotel room, where the party people from 'Fantasy' live it up in the next room. Lonely, pouty Aiko gets upset and bangs on the wall (a shot stolen from the previous PV) as if to say, 'hey, some of us are trying to break up with our boyfriends here!'.
She calls 'flannel man' with her cell-phone and he says 'it's over', and she sheds some acting tears as she hangs up the phone. Look, flannel man, it's your loss.
Aiko slumps down in her hotel room which is HUGE by Japan standards, and it probably cost 100,000 yen for one night, so I hope flannel man's paying. Cut to him and he's on a dock, closing his phone, so now he'll probably help Nacchan write a song or something. He walks away and crosses paths with a familiar-looking girl wearing a pink overcoat, tied at the waist, carrying a stack of gifts so tall that she can barely see where she's going.
The guy can't even leave the video without seeing his old girlfriend... wait, wasn't she just on the phone a second ago? Nope, this 'new' Aiko is the third character in the video set, who will be maxing out every credit card she can find in the next PV.
