Looking for Ariya story

Hey there everyone

So I don't really remember the name or concept of this story but I just remember some scenes. Hopefully one of you recognize it and help me find this story.

So Riya is away from ETF and the team hasn't met her yet. Arjun has a habit of fighting in underground wrestling rings to relieve stress. And the moment they meet after xora is as the song "Ye Tune Kya Kiya" from Once upon a time in Mumbai plays.

The scene was so beautiful despite it was written and not shown that I suddenly remembered it today and I want to read this story again.

The story is nearly a continuation of the show. I mean it has the essence of the show characters sketch but Riya is probably badass. So please if anyone remembers it do share.

Also is Ariya Electrons cannot be friends updated and completed? I came to forum after so long. Everything feels changed.
