(this Hak person sounds like a good gay.)?

I'm so confused about one thing... did u put gays instead of guys on purpose?

Make a sequel

I really loved the idea and enjoyed reading this story.

I may be just a bit disappointed though. I mean, this had so much potential and I feel like the two groups just met, exchanged greetings and then went their separate ways. There no significant information passed to the new generation or important revelation except for Zeno's immortality (I could feel the angst, but not I as much as I would have liked)

An advice on the technical side, you could use descriptions to replace the characters' names. As your story is really dialogues heavy (which is totally fine btw) it can get a bit repetitive. Ex: the green haired pirate instead of Jae-ha or the immortal dragon for Zeno.
On a positive note, your grammar is impeccable and your characterization is really spot on.

Thank you for writing this fic, and I look forward to your future works! _

P.S. I LOVED the line "So I turn into a little girl in the future. Did not see that one coming." Nice touch and it made me laugh.

minor typographical errors but it's good!
