Jay was dead tired after almost a week of a packed schedule. He felt that he was constantly moving around from one stage to another without rest. And it took a toll on his body. He got sick after overworking. Though he was dosed continuously with vitamins and a private doctor, he was still a human after all.
Thus, he took one day rest from any practice to recover after he fainted in the backstage after he finished one amazing performance in a music show.
Jay was sleeping on his mattress with a fever sticker on his forehead to cool down his fever. He had a fever dream. He saw Han Hyung pushed him to be the biggest soloist of the generation. They were so in love, and Jay would never think about leaving Han Hyung.
In fact, in that dream, if Han Hyung told him to announce that he was gay and had been dating Han Hyung for years, then he wouldn't even hesitate to do it. Because everything was meaningless compared to Han Hyung.
