A picture of actress Choi Ji Woo and child actress Kang Ji Woo sleeping on the couch while in the filming scene of "Suspicious Housekeeper" was captured.

The production team of SBS Monday Tuesday drama "Suspicious Housekeeper" uploaded a picture of Choi Ji Woo, who plays Bok Nyeo, and Kang Ji Woo, the youngest sibling Hye Gyul, sleepign in the filming scene.

The two in the picture have just fallen asleep while resting on the couch, taking a break from filming. Kang Ji Woo seems as if she's sleeping with a mother. Choi Ji Woo is hugging Kang Ji Woo from the back, as if she is her daughter.

Choi Ji Woo has been sleeping in the car or in the waiting room next to the filming scene only for three to four hours at a time, due to an overwhelming amount of filming.

"Little Ji Woo" has also been enduring the lack of sleep, showing maturity that is hard to see for a child.

SBS "Suspicious Housekeeper" airs every Monday and Tuesday evening.
