The adorable moment was on “King Of Mask Singer.”

There’s no denying that IVE‘s Liz has a star quality that has netizens weak, but a fourth-generation male idol is gaining attention for “going red” and flustered around her.

Recently, Liz has been appearing on King Of Mask Singer, and while she was hidden under a mask, netizens could hear the idol’s unique tone, and they identified her straight away.

In the recent episode, after showcasing her talent, Liz’s identity was revealed, and the idol looked beautiful as she spoke about some of the clues that were mentioned, including her home of Jeju.

One of the panelists during this time was ATBO‘s Yeonkyu.

When they spoke to Yeonkyu, he explained, “Since she had a comeback recently… and she’s causing… quite an excitement… I’ve been staying interested, too.”

Fellow panelist Kim Gu Ra hilariously pointed out, “You’re turning red, son,” while another male voice added, “WHY ARE YOU STUTTERING SO MUCH?”

The poor idol seemed flustered, and another panelist added, “His ears are literally on fire. What are you going to do?!”

Yeonkyu was unsurprisingly even more flustered as he tried to defend his actions by adding, “BECAUSE SHE’S A SUNBAE-NIM…” and he also waved hand at someone in the crowd saying, “You must like her!“

When the video was posted, netizens couldn’t get over how adorable Yeonkyu was and how relatable his reaction to Liz was.

Along with being a sunbaenim, Yeonkyu might have been flustered because even in the previous episode, he had been certain that the contestant was Liz.

It was a truly adorable interaction between the two fourth-generation idols.
