Oh~as long as you're happy I'll be alright~
Oh~don't focus on my tear stained eyes~
Look at the flowers~oh~look at the sky~
You get more beautiful everytime you smile~
Oh~as long as you're happy~there's no reason to cry~

So this is definitely inspired by bts's new album tear and their teaser of fake love. Well not necessarily the video, but the lyrics at the end at least.
