Xiumin sometimes doesn't like being an idol, it's tiring and hard and you have to be so perfect for people to accept and love you otherwise you'll get left behind just like what happened to so many other people who tried to make it but unfortunately didn't. But of course he doesn't always regret the fact that he's an idol now, well he got the fame, money and the success he always tried so hard for, and he also got the members to entertain him. As you can see, Xiumin is a quiet guy, he likes to observe things and keep them to himself, sometimes he does tell others about it but it's more fun to be the only one that knows it all. What he likes the most tho is watching Kyungsoo and jongin. These two as no one knows, or probably everyone does, Xiumin doesn't know anymore, are together. They are a thing. They're dating each other. Yes, they're gay and in love with each other and it's so fun to watch them because they try their hardest not to show it to people but they're so obvious, at least that's what Xiumin thinks. Maybe it's just because he keeps on watching them all the time? Well whatever, what matters is that they entertain Xiumin big time. 
One time for example they went to an award show and they were all sitting next to each other watching people's performances until Kyungsoo stood up out of nowhere and said that he had to go to the toilet, Xiumin shrugged because that's no big deal but the moment Kyungsoo approached jongin and looked at him dead in the eyes Xiumin
