The song, written by Smokey Robinson, talks about a woman who's telling her boyfriend not to fall for other girls, because they don't want him, and their love isn't true, but hers is, so she's telling him that he "better wake up" before they "break up".
The single was the first of a trio of Top Ten hits with Robinson in the year (followed by "You Beat Me to the Punch" and "Two Lovers"). It featured vibraphone production and brought out a softer sound in Wells' voice that hadn't been shown in her earlier releases.[2] The single was the highest-charting single of her career at the time.
