Lee Su-a

Shin-hye, Mi-yeon, and Hae-young are three vivacious women who help each other through the tangles of their romantic lives, from tentative first dates to Viagra-taking husbands and one-night stands. Being 40 proves that they're not past their prime.

Once known as the frontman of the rock band Ambulance during his college days, Seung-min now lives a quiet life running a small instrument shop. One day, his legendary first love Bo-na, the girl he never even had the courage to confess to before she suddenly disappeared, unexpectedly reappears in his life. From that moment on, Seung-min's heart begins to race again. But as old feelings resurface, he finds himself trapped in an awkward predicament: a secret he must never let his first love discover… no matter what.
