Heart of Power: Mr. President’s Secret Lover

Claire, a country girl who works at a fried chicken restaurant, accidentally entered the hotel suite where US President William is staying. After using her body to detoxify him, she helped the president, who was shot, avoid pursuers. In order to repay their kindness, the two formed a contractual marriage, but Claire mistakenly thought that William was just a substitute bodyguard for the president. It wasn't until Claire was kidnapped by a gang that William arrived with his special force.
