Okay, since a lot of people have asked about the context of the story this MC is in, I'll take a crack at describing it. 6: But A, it feels a little weird because this is just a proto-story; it mostly exists in my head at this moment in time and I still don't know that much about the details.
And B...you're probably going to find that the existence of close friends in her life doesn't have a whole lot to do with this. ^^; Like, yes, of course the strength of her relationships will affect her opinion on the central conflict, but there's a reason I see it as more of an incidental facet of her life and less of a foundational pillar of her character.
Summary
So...as some of you may have guessed, this is an action-oriented story. To give a brief synopsis: human beings are used as avatars for extra-dimensional aliens to play a fantasy MMORPG. ^^ Each pair-up is voluntary, and the humans benefit from the aliens' ability to manipulate causality in their favor, based on how many 'points' they can rack up 'in-game'. This is the 'part-time job' I mentioned that the MC is occupied with.
As for the actual plot: over time, a lot of the human avatars in her area have been getting killed. Like, they are actually dying IRL, and this is not something that's supposed to happen. From the aliens' perspective, people's accounts are randomly getting deleted, so they're upset, too. And most of the story consists of figuring out who's behind it and resolving the problem.
Now, this is where things get fuzzy...as I said, I haven't actually worked on this story very seriously. ^^; But my current idea is that there is a certain player who doesn't want humans to have free will anymore, and their murder spree is an attempt to collect enough causality points to give the aliens full control over the world (and of course, their alien partner is totally on board with this). Eventually MC will have to confront this guy, there'll be a big final battle, maybe some anime speeches...you get the idea.
...And there you have it.
And now that I think about it (honestly, talking through this has helped a lot) I feel like her position in life of appreciating people and liking to be around them, even when these feelings aren't reciprocated, makes her a good foil to an antagonist who thinks people are so worthless they deserve to be made into mindless puppets.
Of course, yes, a typical 'power of friendship' MC would be a good foil to that, too, but this idea is more unique and I'm doing it instead. =p
P.S. I have this sneaking suspicion that some of you only asked for this context so that you can point at things and say 'oh, but look, these people could be her friends! Why don't you just write that?' As in, instead of what I actually want to write (see the title of the thread if you need a reminder).
Please...do not do this.
Really?? Because my experience has been the EXACT opposite. o_O The 'power of friendship' isn't a trope for no reason...it's everywhere. In everything.
'You don't have anything if you don't have friends', 'I would die without my friends', 'no friends no life'...these are the messages I've been bombarded with since childhood. That made me feel like I was some kind of freak or failure who shouldn't want to be alive.
And I'm not going to downplay the importance of social interaction for human beings as a whole...I've been through psychology classes, and I'm not stupid or self-centered enough to think that my experience represents the majority.
But, you know...I think people deserve a break from this messaging, occasionally? ^^; Just once in a while? People who are actually lonely and don't want to be reminded of what they're missing, or people who are just solitary and fine with it...or people who have bad friends. They deserve a break from constantly being told that other people that they can't control should determine the value of their lives.
Maybe this is just a neurodivergent thing...like, physical contact is good for most humans, but people who can't stand it still deserve to have a voice. Speech is important to the development of most humans, but people who don't speak still deserve to have a (figurative) voice.
We get that we're not the majority, you don't have to preach at us about how awful it is for neurotypical people to go without the things we spend our lives without, for the most part. But that doesn't mean our experiences are invalid, or need to be censored.
...I simply do not agree with that. :T I've been making stories for characters for years now, I've never had any complaints, and it's fun and works well for me and I'm going to keep doing it.
In general, I don't think the order in which you do things as a writer matters. What does matter is building outward from the ideas you start with, whether they're characters or events or even just settings, to create something that an audience can enjoy. And I think you should limit your advice to that process...y'know, the part writers actually spend time on and have control over.
