Music Video Appearances

  • Hey My Love (2021) – GREENER


“Frankly speaking, it was like playing a level-up game watching the number of my followers go up each time I posted a video. Back then, I was all holed up in my own room. All I did was creating videos, analyzing the contents and harshly training myself every day.”

“Looking back, I think I’ve always wanted to prove myself. It was all about making the best out of the given 24 hours. I just had to do everything right.”

“You know, my life remains the same, but so many things surrounding me have changed.”

“I still remember the first time I uploaded my first video, for which I used the duet function. It immediately hit several hundred thousand views, and the second video racked up a million views. But ironically, I felt isolated at the same time because the comments were all written in English by global users. It was like, ‘Who are all these people? I don’t even know their faces,’” 

“I wasn’t somebody who could dance and pose in front of a camera. It took me a lot of effort to be able to do that.”

“To be honest, I think I was more outgoing before I started TikTok. As a creator, I think I work 24 hours. Sometimes I overthink and stress myself out, and I still feel awkward with all these talk and spotlights around me.”

“I’m just trying to be myself as much as possible.”

“As platforms may not be eternal, I thought I needed something of my own. So I’m planning to launch a new game which uses my own brand sometime next year. It’s already in the process of development. Me and my company will keep cooking up something new. But most importantly, I will continue communicating with my fans as a TikToker.”

“Actually, I was trying to enter a company. ‘Cause I majored in audio engineering from college. I was preparing to be a sound engineer at a studio, but all of a sudden this [TikTok] platform started booming. I decided to throw my major away.”
