"우리 사랑하지 말아요" Translation of lyrics

Question

I'm trying to learn/understand the lyrics of this song "우리 사랑하지 말아요", but I don't understand the end of this line:

사실 조금은 두려운 거야

Could some nice person help me? :)

I know that the verb to be afraid is 두렵다, and that "거야" is one of the future tense conjugations, but I don't understand why this sentence would be in the future or why the 운 comes after 두려.

Thanks in advance!

Here is a translation of the song that looks pretty accurate

https://ilyricsbuzz.com/2015/08/bigbang-lets-not-fall-in-love-lyrics.html

우리 사랑하지 말아요 아직은 잘 모르잖아요
사실 조금은 두려운 거야 그대 미안해요
우리 약속하지 말아요 내일은 또 모르잖아요
하지만 이 말 만은 진심이야 그대 좋아해요

Let’s not fall in love, we don’t know each other very well yet
Actually, I’m a little scared, I’m sorry
Let’s not make promises, you never know when tomorrow comes
But I really mean it when I say I like you

-거야 is not necessarily future tense and 두려운 actually indicates this is not future tense

-거야 is most likely a more shortened informal version of 거예요

뭐하는 거야 = short for 뭐하는 것이야 (or 뭐하고 있는 것이야 in this case) 것 is a pronoun, used like 이것, 저것, 그것.
