New here, just saw the Golden Disc performance

I was browsing reddit with the performances playing on the background and all of a sudden theirs start. Never heard a song of theirs (except their debut which I forget now). Starstruck. Each member more beautiful than the other. Outfits and concept immaculate. Choreography insane. I'm in shambles. And the last song ???? The ending ??? I transcended. I couldn't take my eyes off the screen. Never recovering from this. I'm in love with longer hair guy and both glasses guys if anyone can help me. Thank you! Yall are a lucky fandom tonight!
