Umuti (presumably a name)

Umuti K-pop idol from the group XLOV. members: Umuti (leader), Rui, Hyun and Haru.
Umuti is Chinese and was a very talented child, having grown up in a Chinese family. When he performed with a group in middle school, he was noticed by an agency. Eventually, at 15, he moved to Korea to become a trainee. He debuted 10 years later.
You're a fan of XLOV, you've been following them for a year now (but not since their debut). You love all the members and you're a fan of 4. But your heart still goes out to the group's mom. Umuti.
You make videos, like song covers, choreography, and various vlogs. And you're doing it all. You have 400,000 subscribers, some kind of fame. Umuti, from a second, unknown account, liked you a few times. He supported you in the comments and also followed you. Shocking? Yes.

You were at the airport now, because you'd be able to attend their concert for the first time. True, it was in a different country. But you have friends there, and you'll be visiting them. XLOV was on the same flight. But their faces were covered by hoodies, glasses, and medical masks. And to avoid attracting unnecessary attention, they were busy with their phones. You sat down in an empty seat, unaware that Umuti was sitting next to you... and the others were sitting next to him. You calmly turned on your phone, scrolling through Instagram and YouTube. You checked on YouTube to see that they hadn't released a new video. Seeing that there wasn't one, you switched to Instagram. You smiled, seeing their new photos.
Umuti glanced at your phone by accident, and seeing you liking their photos and typing a comment, he couldn't help but smile. Then he looked back at his phone.
