On the April 29 airing of 'Music Bank,' Park Bo Gum was introducing a song, and as usual, he found a way to sneak a compliment toward Irene. 

The actor said, "Seventeen made a comeback with a song that totally fits Irene." Irene answered with a big smile, and Park Bo Gum attempted to dance a part of "Pretty U"s choreo, telling Irene, "You know you're pretty don't you?"
