"Come In" is a duet song by HyunA and Gayoon, and expresses a woman's straightforward feelings toward a man. Its said the songs was deemed too provocative for broadcast due to its sensual lyrics by SBS, while MBC has given it the okay sign. 

A Cube Entertainment rep told Star News on the 14th, "We took into consideration each part of the new title track and follow-up tracks but the SBS broadcast judging panel deemed 'Come In' as unsuitable for broadcast."

"We think it's because the lyrics were mature... In the agency's perspective, we think it is a metaphorical expression but everyone thinks differently... We received the approval from MBC and we are currently waiting for KBS' decision."

According to the flow of K-pop these days, we didn't think 'Come In' wasn't crossing the line so much, so we took that into consideration... We will not make any adjustments," revealing that they have no intention to change any of the song.
