There's a scene that happens with Mikan and Ryoko in OAFC that I semi-want to ramble about so. It's beneath the cut because spoilers.
Basically, Mikan makes the claim that she knew Ryoko first, in a sense. That she'd seen Ryoko and Matsuda together frequently, and that after Matsuda disappeared and she became Junko's nurse, the change in her was so striking that Mikan wanted to make her better - to make her more like Ryoko again.
I'm still not sure that Mikan is entirely telling the truth here. She might be; Mikan doesn't sense the fact that Ryoko and Junko are different (something both Ryoko and Junko insist is true). She believes that Ryoko and Junko are one and the same. So where she loves Junko, she by nature will also love Ryoko, even if Ryoko never gets her memories back, even if Ryoko chooses to be Ryoko instead of Junko if/when she does. The above is basically Mikan saying I loved you first, before Junko.
And I have a feeling she's lying. I think Mikan would choose Junko over Ryoko, if she was given the choice. I don't think she's lying about seeing them as the same.
But even if she is, I like that this implied that Mikan chose Junko just as much as, if not before, Junko chose her.
That it wasn't just Junko deciding that Mikan was hers.
Mikan chose her, too. She chose her first. That Mikan has always been her nurse trying to get Junko back to the self that could be happy.
Idk. She might be lying. But. I think it's interesting.
(It's also - there are a lot of parallels in the Junko/Mikan relationship and the Junko/Kyoko one. Some of these are intentional on Junko's side. But there very much is a sense of Junko being vulnerable and weak (or feigning it) as a result of losing Yasuke that draws both of them in. It's possible that she picked up on that from her relationship with Mikan and then intentionally used it with Kyoko, even in the moments where she was being truthful.)
