Eunchae was very excited about the newest episode of Star Diary as she revealed that aespa’s Karina was the next guest.

When Karina entered, the bond between the idols was clear.

Every small moment of the video showed just how close Karina and Eunchae are, whether it was how many times Karina had been on the video or the small gestures.

Of course, friends can tease each other and Karina wasn’t afraid to have some fun with Eunchae.

During the video, the duo was asked what they had each other saved as in their phones.

At first, while Karina explained she didn’t know how Eunchae had her saved, she teased that Eunchae’s name was saved as something cute.

Eunchae surprised Karina by explaining that her name was saved under “Yu Jimin Unnie,” which is her real name, and the aespa idol seemed “upset” by such a basic name.

Karina playfully threw the book, pretending to be “heartbroken” after she found out the name under which she was saved.

Eunchae explained that she changed it as soon as she saw Karina’s nickname for her, adding that the new name was cute. Karina revealed the “cute” nickname she had for Eunchae on her phone, and it was a cute play on her name with “Eungchae” and a baby bottle emoji.

After seeing the cute name, Eunchae explained that she quickly changed Karina’s name to “Yoo Jji Min Unnie.”

When the video was posted, netizens loved how adorable Karina’s reaction was to her name on Eunchae’s phone and it showed just how close the two idols are that they can have this sort of relationship.

As always, Karina and Eunchae show how close female idols from different groups are.
