Sua (Ter - Chantavit Dhnasevi) and Jib (Ice - Preechaya Pongthananikorn) are like any other couple in the world, with one exception: for the past 5 years they have kept their relationship secret since the bank where they work has a strict "No Fraternization" policy. It's no big deal until they decide to get married. The only problem: Which one of these two Type-A overachievers will put marriage before career and resign? With neither willing to take the leap of faith, they both turn incident into opportunity when an ATM glitch in Chonburi province cashes out over $130,000 baht. The terms are simple: whoever can recover the money first stays at the job. The couple turns into no-holds-barred competitors. Who will literally "go big" in their career or "go home" in this romantic comedy about what two people will or won't do for each other in the name of love? It's the age-old battle of the sexes, but this time, how can victory be easily declared in a war where there are no more traditional "rules of engagement"?
