Yoona's mystery item hint sparks curiosity on 'Check-in! Idol Bingo'

In the Mnet variety show 'Check-in! Idol Bingo,' scenes were released showing cast members conversing as they attempt to guess mystery items hidden inside a suitcase.

The meaning behind the 'Lee Bo' and 'relaxed humming' hint

According to episode 12 of 'Check-in! Idol Bingo,' which aired on September 24, 2026, the cast exchanged various questions and hints to identify essential beauty items packed in the suitcase. During the episode, one cast member provided a cryptic hint for an item, stating, "It is relaxed when with Lee Bo. So, a bit of relaxed humming."

As soon as the hint was delivered, anticipation for the correct answer grew among the cast. Tension heightened as members reacted with, "I have a huge feeling about this," followed by comments directed toward Yoona.

A process of speculation through questions and answers

The cast continued to ask questions to narrow down the item's characteristics, such as whether it makes sound or emits light. One member replied, "It doesn't emit light," while another noted, "I've never seen it emit light," helping to define its physical appearance. Additionally, they debated whether the item's name consisted of "four characters or more," to which the response was, "I don't think so." During the questioning, some wondered if the item was related to Wonhee's game, though opinions were split on whether they had seen it before.

The cast demonstrated their intense immersion in the game, with one member remarking, "I've been blinded by a million won." The early part of the video focused on members comparing experiences and hints to uncover the item's identity. The video's title drew attention to the cast's intense energy by mentioning 'Darkened Yoona.'

Meanwhile, 'Check-in! Idol Bingo' is released every Wednesday at 5 PM on Mnet Plus and airs every Thursday at 7:50 PM on Mnet.
