Translation of the song lyrics Nobody knows - GOT7, Youngjae

Nobody knows (original)

한번 웃어주고 말아
오히려 편해 그게 더
딴말 안 나오니까 너무 힘들지만
그냥 웃어주고 말아
결국 모두가 똑같아
내게 원하는 건 같아
그대로 해줄 게 그대로 해줄 게
뭐든 너 바라는 거
쉽게 생각하겠지
＂쟤는 행복하겠지＂
하지만 네가 틀렸어
Nobody knows
아무것도 너는 몰라
나는 외로웠어 혼자
이런 모습 보이기 싫어
감춰만 왔어
이젠 그런 표정 안 봐도 돼
그것만으로도 난 충분해
Nobody knows, nobody knows
나는 이겨내 볼게 혼자
눈물이 나도 울어선 안 돼
내게 집중할 테니까
이때다 싶어 더 조여올 테니까

Nobody knows (translation)

smile once
It's rather comfortable, that's more
It's so hard because I can't say anything else
just smile
After all, everyone is the same
it's like what i want
I'll do it for you, I'll do it for you
whatever you want
you'd think it would be easy
“He will be happy.”
but you are wrong
nobody knows
you don't know anything
I was lonely alone
I don't want to look like this
I've been hiding
I can't look at that face anymore
that's enough for me
Nobody knows, nobody knows
I'll overcome it alone
I can't even cry
'cause you'll focus on me
I want it this time, so I will tighten it more
