Should I complete my unfinished work from 4 years ago?

Hello. When I was younger, I created a Wattpad account and wrote a short story, after it I attempted to write a novel.

But then things happened, and I couldn't complete the novel, nor inform the readers. It have been 4 years, and just yesterday I managed to retrieve my account.

Looking at my old work left me feeling both embarrassed and proud. But also I was hit with my readers comments of back then " I miss your story ", " When is the next chapter? ".

Of course these comments are not recent, and I felt this pull again for writing. I think it never left me, really.

Yet, I'm kind if hesitant on how to approach it; should I complete the novel, then publish all the chapters, and write an apology. [ sorry I'm late, here is the continuation.]??

But like it has been 4 years, YEARS! I doubt my novel is remembered, yet … I don't have the heart to abandon it. Please help? Thank you in advance.

Also, I apologise if there's any mistakes; English is not my first language.
