He thinks he likes the leader of his band's ex boyfriend, the pink-haired guy who was a former band member. But he'll definitely fall for the mc, especially once he realizes the mc's is "secretly" one of his fans, and once he finds out the mc's completely innocent of the charge of "interfering" with the band leader and former band member's relationship, which was the one "crime" that the violet haired idol had thought the mc was guilty of (enough to try to lead him on and take advantage of him), his guilt will seal the deal, and he'll try to date him for real... (unless the mc finds out and yeets him, in case of which I *definitely* wouldn't blame him)
