Eren is a disciplined, cold, and successful advertising agency manager. His complete opposite, Şirin, works under him – a clumsy yet creative employee with a colorful personality and a deep love of cats. Conflict has defined their relationship from day one: Eren lives by order, while Şirin thrives in chaos.

When Şirin is fired after accidentally sending a disastrous email, fate intervenes. Eren’s mother, Güzide, claims she is terminally ill and begs her son to get married. Desperate to make her happy, Eren devises a fake engagement plan – and the only “suitable” candidate he can find is Şirin, whom he dismissed just days earlier.

Reluctantly, Şirin agrees, driven by financial struggles and family responsibilities. Thus, two opposites are drawn into a game neither wants to play. At first, Şirin’s clumsy honesty wreaks havoc during meetings with Eren’s mother, but her warmth and sincerity win hearts wherever she goes. Meanwhile, Eren starts to see that Şirin may be far too genuine – and far too human – for the lie they’re living.

What starts as a strictly defined “love game” quickly spirals out of control, as real feelings take hold and love pushes these two opposites together at full speed.
