On tvN 's December 6 premiere of Rented in Finland , Cha Eun Woo gave viewers a rare glimpse into his family. The show highlights the rural adventures of Lee Je Hoon, Lee Dong Hwi, Kwak Dong Yeon, and Cha Eun Woo in a remote village in Finland.

In preparation for this trip to a rural area without electricity, internet, or running water, Cha Eun Woo practiced cooking at home. When his mother suggested that he cut up carrots for decoration, he reacted with comical exaggeration. Later, while stir-frying meat, he showed his considerate side by asking his mother to be careful of the oil splashing.

His culinary training continued with the support of his younger brother, who shares the same name as actor Lee Dong Hwi. The audience was given brief glimpses of Cha Eun Woo's mother and brother, sparking curiosity and interest.

In a bonding moment, Cha Eun Woo asked his brother to say a few words, to which the latter warmly responded, “I always support you, hyung.” Their close bond was evident as his family showered him with compliments on his cooking skills, showing a loving dynamic.

A post in an online community showing photos of Cha Eun Woo's brother also created a buzz, with netizens marveling at his good looks that rival that of his famous sibling.
