The lyrics, which you could straightforwardly call a song about an affair, convey the pain of loving Megumi Mori yet being unable to see her, sung from a woman’s perspective, while Takenawa responds as if replying to that woman’s feelings—stuffed with the kind of frank excuses you often see in dramas.

She wants to forget that painful reality… yet she simply can’t.
