Rak Salap Lai

This is the story of “Cream” (Fonthip Watcharatrakul), a plus-size fashion designer weighing nearly 100 kilograms, who dreams of becoming a world-class designer. One day, that dream comes within reach when she is chosen to join a major project that could become her gateway to walking the path toward Fashion Week runway success.
The problem is that she has to work with “Tul” (Suppasit Jongcheveevat), her first love from high school — and someone who remains a painful emotional knot in her heart. Unwilling to let this opportunity slip away, Cream secretly arranges a hidden swap with “Cake” (also played by Fonthip Watcharatrakul), her glamorous and completely opposite older sister, to act as her stand-in.
But the situation quickly spirals out of control, and both Cream and Cake end up getting swept into the chaos. To make matters even more complicated, “Pete” (Athit Tangwiboonpanit), a charming, flirtatious executive from a famous fashion brand, unexpectedly falls hard for the older twin.
How much confusion, turmoil, and thrilling chaos will this upside-down secret deal bring into both of their lives, when two twins who are complete opposites are forced to switch places in order to conquer this mission of secrets — and love?
And in the end, can this switched-up secret deal turn into the right love deal with the right person?
