<human>: Can you give me the gist of the text in a nutshell?

We have been going out for roughly 2 weeks, but had mutual feelings roughly since mid February. It's going well, and she lives relatively close (6ish minutes walking distance, 2 min driving).

So this Saturday, I (after waking up at ~11 pm from a nap) decided I would go to her house (I've been there, but never inside/never met her Korean parents) to say goodnight in person, trying to make up for not coming over, since I said I would come over at 8~9 pm.

So there I was, nearly midnight, at her house. She told her dad, who was awake, that I was outside. She invited me in briefly to say hello to her dad, and then her dad and she began arguing in Korean (I'm chinese). She translated for me later that she would be in trouble.  

I talked alone with her from 15 minutes and then came in to apologize (I learned how to say "i'm sorry" in korean during those 15 minutes). He then spoke in english saying to her "You're in trouble," "I'm telling your mother," and "Do you know how late it is?"

Afterwards, I said goodbye. In the morning, my gf called saying that if I pulled something like that again, her parents would make her break up with me.  

For the next 4ish hours, she won't be home, and I was wondering whether or not I should go to her home and apologize properly, alone. But doing this, I fear they might say something like to never come here again. 

I could also wait it out and never do something like that again, and maybe regain some favor, but I would feel threatened by the idea of never resolving the issue formally.

A third option would be to talk to her parents with her later tonight (I'd say roughly 8 pm), and sit down and apologize...

*We are young, but this issue is more of me not wanting her parents to look at their daughter's boyfriend in negative light/ as a bad influence.
<bot>: First time meeting her dad was midnight outside her house. Bad first impression might force her parents to break us up. Should i formally apologize alone, with her, or do nothing?
