[TOMT][Youtube Video][Song] Asian girl with glasses sings acoustic. Lyrics include "I love you". Toy trumpet involved.

Saw a video posted on Reddit a year or two ago, the video was of a girl singing mostly in an Asian language (maybe Korean), with the only English lyric being "I love you". She mostly strummed an instrument, perhaps a ukulele, and played a small solo on a toy trumpet. Slow paced song, completely unplugged, and recorded amateur in a bedroom I think. She wore glasses, and sung in a style similar to Cocorosie (which I think was mentioned in the comments).

Her channel is quite popular I believe, with a diversity of content.

I would so much appreciate any help, I've searched extensively, but can't seem to find it.

Thanks a lot!
