Love 50% (2010)

The paths of two strangers - Haney, a free-spirited girl, and Wen Kai, a risk-averse insurance actuary - collide one Valentine's Day when they both walk into the same jewellery shop on the day the store is offering a 50% discount for couples, if they both shop at the store. Haney hatches a plan that they both pose as a couple to get the discount. But their plan backfires and throws them both into an adventure that proves that love lurks in the unlikeliest of places.
