Synopsis

Behind the dazzling lights of the fashion world lies love, secrets, and tangled relationships filled with chaos and complexity. Prim (Tipnaree Weerawatnodom), a talented director, finds fate playing a cruel joke when she has to work again with Bambi (Rachanun Mahawan), her ex who disappeared without a word. This time, Bambi returns asking to be friends, but the question remains: can two people truly be “just friends” when they still share the same bed? While Prim navigates this old flame, Shasha (Pansa Vosbein), a confident top model, hides a fragile side drawn to Gorya (Pattranite Limpatiyakorn), the stylist who plays hard to get longer than anyone Shasha has ever chased, and the more she is rejected, the more her desire burns hotter with every encounter. Meanwhile, Min (Benyapa Jeenprasom), a producer burdened by life and expectations, stands at a crossroads between marrying her long-term boyfriend and following her own dreams, until she meets Praew (Rattanawadee Wongthong), a bartender who opens her eyes to a kind of love she’s never known before.

Six women. Six hearts. Entangled in emotions too complicated to define. The only rule to protect their hearts is simple: Don’t fall in love with her.[4]
