Girls' Generation Taeyeon and SHINee's Minho have been caught showing off their gwiyomi (cute) sibling-like affection.

On Saturday afternoon, Taeyeon had uploaded a photo on her Instagram, along with the caption: "This is gwiyomi Minho who always comes into Noona's (older sister) waiting room chattering away. From now on, I'm counting on you for 'Music Core'! By the way Minho, you definitely make the suit your own."

The photo shows the two in the waiting room of the broadcasting station with Taeyeon hard at work applying manicure polish to Minho's nails. The two, who share similarly cute features, certainly look as if they could be siblings. The warm, affectionate manner in which Taeyeon diligently works at applying the manicure is grabbing much attention online. 

Internet users who saw the photo had various responses such as, "I'm totally envious of the two," "Overflowing with cuteness," "They make a cute couple," etc.

On Saturday, along with broadcaster No Hong Chul and actress Kim So Hyun, Minho began his run as host for the MBC program, "Music Core."
