Orm Kornnaphat, the elegant yet headstrong heiress of one of Thailand's most powerful hotel empires, is known for her perfect life - wealth, poise, and a fiancé chosen by her family to secure a business merger. But on the eve of her engagement party, Orm escapes - disguised in a hoodie and sunglasses, she drives off into the night, determined to find freedom. A sudden car accident on a remote mountain road changes everything. When she wakes up in a Hong Kong hospital, she has no memory of who she is - only that a glamorous woman is sitting by her bedside, pretending to be her wife. That woman is Lingling Kwong, a dazzling actress-model who's been the media's obsession for years - and currently caught in a scandal that could ruin her career. When paparazzi mistake the injured Orm as her secret spouse, Lingling plays along to save her public image. Now, the two women are stuck in a hilarious, heartwarming, and tension-filled fake marriage - one trying to remember her past, the other trying to forget hers. But when flashes of Orm's old life begin to return - and jealousy stirs as Lingling's ex resurfaces - both women must decide if their "accidental love" is just a cover-up... or fate itself.

Orm is the eldest princess of the royal family - a "rebel with a silver spoon" who's grown tired of being a living doll for the public eye. She's adored by the people and the tabloids for her bold personality, striking style, and fearless attitude. But deep down, she feels like a prisoner of the palace and her family name. Ling is the daughter of the richest industrial magnate and a powerful media tycoon. She is the flawless heiress - always composed, calculating, and impeccably reputable, used to controlling both people and situations.

"I Think I've Seen This Film Before (And I Didn't Like the Ending)" is a tender, aching tale of love, loss, and the cost of dreams set against the glimmering backdrop of fame. Five years ago, Lingling Kwong and Orm Kornnaphat Sethratanapong were more than just Thailand's most beloved on-screen couple-they were soulmates, tethered by a deep, unspoken bond that transcended the scripts they acted in. Off-screen, away from the cameras and adoring fans, they found solace in each other... until the weight of ambition pulled them apart. Lingling, now 35, chased international stardom. She left Thailand behind for global screens, making her name in Cannes and Hollywood, but also leaving behind the woman who made her heart feel like home. Orm, now 28, stayed in Thailand and blossomed into a national icon-the pride of Thai cinema, fierce and radiant in her own right. For five years, they worked on different continents, never crossing paths, never looking back-until now. Their former management company organizes a grand anniversary special for Channel 3, reuniting legendary on-screen pairings. When Lingling and Orm are cast together for a commemorative short film, the reunion stirs everything they tried to bury. Old wounds reopen. Lingering feelings resurface. And the question hangs in the air like the last scene of a film never shot-what if the ending didn't have to be the same this time? In the soft glow of studio lights and between the echoes of shared laughter and painful silences, the two women must confront the reality of what they lost, and whether love still has a second chance when the curtain rises once more.
