It's a song written by Fly Tzuyu. And every time I listen to it, I either cry or get teary-eyed. She's been through a lot but she's never given up. I'm proud of her.
Hello there, just want to give some infomation about "One Love" One Love used to be an unidentified song for 10 years, but Tzuyu used it in her album and that's how the "lostwave" community found out it came from Kamillie, the writers of One Love. It was a leaked demo that was on a K-Pop forum (I think) The demo version is still online if you want to hear what has changed. Sorry if this comment is bland or something, just wanted to give out some info about the song.
