Help me find this song

Hi everyone,

I've never posted here, so forgive me if this goes against one of the subreddit's rules.

There was this Japaneese rock song that I used to listen to a few years ago, and its been driving me crazy trying to find it. I don't remember how the song goes, but I remember the music video. The video was set in a white hospital, and it had a focus on like hopeless young-ish patients I think? I also do remember that the artist was in a video by the YouTuber Akidearest, and that's how I had found the artist.

If anyone happens to know the video I'm referring to, that would be fantastic!
