The Other Woman
I've had this idea for a while - basically, MC meets Non!MC Reader in between Caleb leaving for flight school/DAA/FSF/whatever and the main story and we become MC's bi awakening and her first (because why are we limited to the LIs? Why can’t we take a crack at MC?). This is a scenario where MC is on a date with one of the lads, we meet her again, and openly tease/flirt with her while hinting at our history (this ended up being more of an OC than a self-insert; sry about that) Hopefully I portray the guys' reaction well...
Zayne:
He's chill about meeting an old friend of hers. He acts normal, polite, if a bit stoic.
Is he surprised to learn that she had a lover? A bit, but it makes sense and he doesn't think much of it.
He is a bit surprised to learn that she's bi, but he doesn't show it. He wants to make sure she knows that he accepts her for who she is, even if she wasn't ready to tell him yet.
It's only when you're openly flirting with her that he finds a moment to cut in with something like "I apologize for interrupting, but we have plans today".
You'll look at them as if just connecting the dots (you know but you like being a little troll) and are like "Oh are you guys together?"
You gush about how cute they look together and how happy you are for them, then add a little "She's a lot of fun in bed" comment.
While she's blushing like a madman, Zayne's only indication of your comment is a slight increase in pressure on wherever he's holding her.
He's still polite enough to either wait for an opening to leave or create an opportunity.
"I'm really sorry about her, Zayne." "It's alright. I'd just prefer if she weren't so... brazen."
If you see each other again, he'll still be polite, but he may give you a pointed stare if you talk inappropriately.
Xavier:
He doesn't think much about it at first. She has plenty of girlfriends at work after all. It's only as you get more openly flirtatious that he starts feeling uneasy.
When you drop the fact that you used to date her, he's blown away. He won't make a huge deal out of it, but he's freaking out inside. She likes girls, too? And you used to date? He's even less happy that it seems you broke up amicably.
Silently fuming as you flirt with her. Doing his very best to excuse you, but you catch onto him and trail along. Think Charlie, but twice as bad.
When you casually drop the fact that you were her first, oh, he's done. His fight or flight instincts kick in, and he teleports away with her, leaving you to chuckle at your mischief.
They have a long night as Xavier reminds her who she's with now.
His possessiveness goes out of control now that he knows he has to compete with girls, too. Even female coworkers suddenly find themselves getting the cold shoulder (MC is cursing our existence rn).
She has to be the one to keep him away from you, otherwise, it will end in a fight.
Rafayel:
At first he’s chill about meeting someone from her past.
But as the conversation goes on and things are slowly revealed, his head is whipping back and forth between the two of you like he’s watching a soap opera.
Once he feels confident enough about his assumption, he’ll interrupt with “YOU’RE GAY??!!!?!”
Goes on a rant about how she’s lied to him, betrayed him, kept a huge secret, etc. He makes sure he’s over the top even for him so she knows he’s not actually upset.
The two of you watch him, her with exasperation, you with amusement. When it seems like he’s dying down, you lean over to her and loudly whisper, “Imagine if he found out we slept together.”
He goes still. Then calmly, a complete 180 from how he was before, he’ll walk up to her-
-and throw her over his shoulder, running away and hollering about how he won’t let you corrupt his bodyguard while she’s demanding he put her down. You’re bursting out laughing the whole time.
You get together with him quite often, and you two become good friends. You feed off each other’s energy well - he’s the sassmaster and you’re the instigator.
“A match made in hell,” she’ll tease. “I think it says something that you dated us both then, darling.”
Sylus:
You cannot catch this man bothered. He just treats this with his usual amusement.
It’s not like he didn’t think she never had any other relationships, it’s more like he didn’t consider it. But he’s confident at where he was with her.
He also wasn’t expecting her to be bi; it wasn’t something he considered in either life. But he certainly isn’t judging. He’ll love her no matter what.
I can imagine him leaning towards her ear and saying something like “You have quite the interesting friend, kitten.”
You snort. “Kitten, really? That’s what he’s calling you? I guess he doesn’t know what you like to be called in bed, huh?”
Rather than get angry, he’s intrigued. Especially since she looks so embarrassed. “Really? Please, do tell.”
You and Sylus end up getting along for the sole reason of embarrassing and flustering her. You’ll say things so raunchy until she either turns into a tomato or runs away.
Caleb:
He’s already semi-hostile towards you. A friend of hers that he doesn’t know? Immediately sus.
When he puts together that you two dated? Obviously he’s devastated that he isn’t her first relationship.
But he’s also having an existential crisis as a lot of things from their childhood are suddenly getting reshaped.
She obviously told you about the childhood friend she grew up with, so when you figure out they’re dating? Oh it’s over for them.
“Really? You’re dating your ‘gege’? How naughty~ Then again, we got into some naughty stuff, didn’t we?” Oh Caleb is struggling.
Now I headcanon him to be a good people reader, particularly when he was in school. So he can tell you’re just doing this to mess with him and you’re not actually a threat.
But you’re someone intimate from her past that he never knew about. You’re basically rubbing it in his face and he is definitely fighting demons not to give you a few love taps with his right hand like the possessive man he is.
He barely waits for a marginally polite excuse before excusing you and moving on.
Definitely devotes some surveillance gear to making sure you never run into him or her again.
