On March 22, KST, Apink's Eunji uploaded a cover of Younha's "Event Horizon" on her personal YouTube Channel, singing it one key higher than the original song. 

This content came to pass when Eunji previously competed in a 'Billiards match' with the editor of her YouTube channel and lost. The editor pushed for the cover of 'Event Horizon' by receiving opinions from fans. Through the introduction of this video, the editor said, "We have prepared a cover video that received the most positive response among Dreamies comments. Please enjoy it."

What surprised netizens was Eunji's singing ability. This is because, while maximizing the charm of Younha's original song, she added her own tone to maximize the explosive and affectionate sensibility, completing 'Event Horizon' in Eunji's own style.

The fact that the song was raised one key from the original song also surprised netizens.

In particular, Eunji released the video and started a real-time chat with fans, asking, "Is it okay?" and when fans praised her, she said, "I tried hard to keep my promise. "I had a cold that day," she confessed, giving everyone another shock as to how she sang flawlessly with a cold.
