Lee Da In reacted to her Lee Yoo Bi's latest Instagram post, revealing their close sister relationship.

On December 19 KST, actress Lee Yoo Bi took to her personal Instagram to share some photos of her recent visit to a bagel museum located in London. Dressed in a mini skirt and cropped shirt, Lee Yoo Bi completed her outfit with a cozy, light brown hooded scarf. In the photos she revealed, Lee Yoo Bi posed cheerfully while holding a tray of large bagels. 

Soon after, actress Lee Da In, who is well-known to be Lee Yoo Bi's younger sister, commented on Lee Yoo Bi's post, "[You're] so cute", along with a teddy bear and ribbon emoji. The two actress sisters' interaction on Instagram drew a lot of attention, as they don't always make their family interactions very open to the public.
