Kusuo Saiki Dating Headcanons
Pairing(s): Kusuo Saiki x Gn!Reader
It takes a really long time to get to the point where the two of you are dating. Like 100,000,000 words, slow burn, they finally kiss at the end– sort of fanfic. Honestly, I think Saiki’s a bit hesitant about relationships in general because they seem like a hassle. Everyone else is on thin ice already, the thought of putting effort into a relationship is exhausting enough.
Like with everyone else, he’s pretty indifferent toward you at first, and you only move up to "mild annoyance" status if you stick around long enough. Especially since he’s probably hearing all your thoughts, so there’s that.
Now, onto the actual headcanons. Saiki isn’t exactly the affectionate type. You two probably started as friends, mostly with you bothering him. Even after he realizes he likes you (though he really tries to hide it), nothing changes much. The difference is, you’re the only person he seems to tolerate. Everyone else wonders why you even bother with him.
Sometimes, Saiki gets... freaked out? There’s really no other way to put it. He’s used to being around people who are idiots, so when someone like you comes along—someone who’s rather perceptive—that’s a bit much for him. It messes with his head. Despite being able to hear your every thought, he starts wondering if you’re psychic too.
You can tell what he’s feeling, what he wants, and even do things for him. Sure, he could do all those things tenfold in just under a minute, but for some reason, he finds himself smiling. He even starts thinking fondly of you.
If you were another Nendou, though? He’d probably avoid you, and your relationship would be a slow burn that takes another 100,000,000 words and even worse edging (Not like that). But I digress. Saiki shows affection in subtle ways. Like remembering offhand comments you’ve made about your favorite snack or color.
He’s the type of guy who’ll subtly push your chair out of the way when you’re about to trip or pick up a dropped pen without you asking. He might not say much, but he’ll do whatever he can to make your life a little easier, even if he doesn’t directly tell you that.
I know it might sound like I’m painting him as a deadbeat bf, but honestly? He’d probably be a great boyfriend. He can literally hear your thoughts. He knows what you want, even before you say it. He’s seen (and heard) men ruin their relationships because they thought they knew their partner. So, when you want to grab a treat or have been wanting something that relates to an interest, he’ll know.
He’ll also know (and hear) if you slightly even think he’s good looking on a particular day. He’ll never admit it, of course, but if you get embarrassed thinking about it (since you know he can hear your thoughts), he secretly enjoys that. Seeing you flustered is one of his guilty pleasures—even though he’d never show it.
And yeah, Saiki’s protective. He won’t say it, and he won’t make a big show of it like other people would, but he does care. If something’s bothering you, he’ll subtly step in. Like if someone’s making you uncomfortable, he’ll use his telekinesis to, throw something at them or trip them up—whatever works, as long as no one knows it was him.
He doesn’t like people messing with you, and he won’t hesitate to shut them down, even if he keeps it minimal to avoid drawing attention to himself.
In this following scenario you're another Nendou. He hardly ever gets surprised. I mean, hearing everyone’s thoughts kind of ruins surprises, spoilers for a new tv show, honestly anything for him. But maybe—just maybe—the only way to startle or fluster him is by turning the tables on that. Maybe it’s the first time you show affection in your relationship.
Saiki’s not big on physical touch– we all know that much. If you want to hug him, go ahead, but he’ll probably just stand there like a statue. So, let’s say you somehow convince him to come over to your place, and then you, attempted subtly, suggest that you kiss him out of nowhere.
He’d choke on his drink and immediately try to cover it up. Forget not hearing your thoughts, he literally didn’t think you’d want to kiss him anytime soon. He won’t show it (obviously) but deep down, he’s definitely a little shaken.
Now, in the chance that you two do kiss, (which is chapters later– in fanfiction terms) he’s very hesitant? Like sure, he can destroy the entire Earth if he even wanted to but the idea is still startling. He thinks it over and once he agrees (which is the only kiss you’ll get until the next blue moon) he is admittedly worried.
He’s never kissed anyone, he never planned to so he tries to be collected like he always is. If a satellite suddenly went offline somewhere in space, well that’s nothing to do with him.
Also, an extra that isn’t a dating hc is that Saikis mom and dad love you so much, his dad literally asked if you were actually real which earned a side eye from Saiki. It does get annoying for Saiki, but he’s pretty glad you all get along.
