Frozen Valentine — S1E4

Two former classmates, one an heiress with a past crush and the other a rising star model, reunite when they're cast in a Girls' Love series. Pingrak—formerly a nerd, now a beautiful, ultra-rich heiress to a massive department store empire—once had a secret crush on P'Charm, her former ice-cold senior and a school star. Today, she's a rising model. Back then, she brought her horrible sadness. From a love that was once one-sided between them, the two are suddenly thrown together as the leads in a Girls' Love series.
