My Keldeo is not able to learn Secret Sword via Move Tutor?

Question

In Pokemon Ultra Sun, I have a Keldeo in my party, but when I take it to the move tutor in the Hano Grand Resort for learning Secret Sword, the gentleman just says "come back to me with a Keldeo or Meloetta.", so how should I make my Keldeo learn Secret Sword without trading?

How did you get your Keldeo?

I am doing a randomizer and I caught it. I don't know what the original randomized pokemon was. Will that affect Keldeo learning the move?

---

Is it one of those randomizers where everything is randomized?

---

Probably. I’ve watched someone play it. It’s not legit, I don’t think.

Is it resolute? If yes, then I don’t know

Answer 1

If I'm not mistaken, Keldeo needs to be met "in a faithful encounter" (in other words, via event) to be taught it.
