Joseph Park was going through the fanprose website, when Asa from Babymonster came in, demanding an explanation

After making the trade, he felt guilty about it, but then he looked upon that Ahyeon 005 card and it made him feel things.

Asa finds Joseph and Ahyeon in a compromising position, however Joseph had other ideas for her, as Asa is the main reason for his frustrations and decides to take it out on her while Ahyeon is here for the ride.
