Katsuki's Twin

Imagines/drabbles

This won't necessarily be apart of the story, just ideas that I felt like putting out there, you can also recommend some as well-
(example: if Kirishima was dating Koyuki, how would Katsuki react?)

There will also be an announcement at the end of this drabble, so please looks at that😌.

How do the characters feel about showing PDA with Koyuki?

Katsuki(platonic):
As you can tell in the actual chapters Koyuki is always around Katsuki, he loves piggyback rides. Katsuki may say he doesn't like being that close with his twin, but that's a total lie.

Kirishima:
Kirishima loves PDA like anyone else, holding hands and kissing. Sometimes it can be hard especially when Katsuki is very protective of him, so, Kirishima, out of respect, keeps PDA to a minimum around him.

Sero:
Sero wouldn't mind PDA, probably like the same as Kirishima. Sero wouldn't care if Katsuki was witnessing their affection for each other, he'd probably do it more. Whatever gets Koyuki flustered, Sero would do it a million times over just to see the reaction.

Deku:
Now, since Katsuki and Deku are literally enemies, it's harder to show PDA with Koyuki, so it's mostly when they're alone that they show affection. If they were on a secret date, then holding hands is a must. Deku likes to feel close with Koyuki, he feels more confident knowing he was dating someone like Koyuki.

Todoroki:
Since Todoroki and Katsuki are also enemies, it can be tough at times to show affection to Koyuki, but, Todoroki would kiss him in front of Katsuki just to piss him off more. Koyuki is a little nervous for his sake, but Todoroki trusted in his quirk to guard off Katsuki's.

Iida:
Iida cares about what other people think, so showing PDA is a little harder for him. Koyuki is actually the one who shows it more since Iida is scared. Since Koyuki never cared what other people thought of them, and knowing Katsuki was always on his side to protect him, so show PDA wasn't too big of a deal to him. Iida will only go to holding hands.

Denki:
Katsuki wasn't a big fan of Koyuki choosing him, but that was just because he thought of Denki as an idiot. You'd be surprised, but Denki has is actually a romantic, and loves those kinds of movies, so he is weirdly experienced in the dating realm and makes Koyuki feel special. That being said, Denki loves showing PDA. Everything that Koyuki is comfortable with is on the table. Though a big thing for Denki is having Koyuki sit on his lap, whether in class or not.

Shoji:
Shoji is the affectionate in the relationship, surprisingly. Koyuki shows a lot of affection, but Shoji is on another level. Having more arms than a normal person is a huge plus(yes, that includes moments during sex as well. Now get your head outa the gutter!). Shoji can easily carry Koyuki with no problem, so Koyuki's piggyback ride obsession is like nothing for Shoji. Shoji preferably likes to carry Koyuki baby still with an under his butt and a few others around his upper body. Shoji wouldn't mind showing public affection, and Koyuki will kiss his cheek here and there, maybe someone his neck as well. Since Shoji is a tall person(6'2), Koyuki will jump into his arms to kiss his cheek since he is too short.

Ojiro:
He is pretty basic with PDA, he could care less for it. Although, he loves when Koyuki initiates anything.

Tokoyami:
Secretly, Tokoyami has a human form, and only Koyuki knows that. When they are in public, people don't really think Koyuki would be in a relationship since Yami looks like a bird. So PDA isn't really something he wants.

Mirio:
Since there is a slight age difference, they don't get to see each other much and only showed a little PDA here and there, but when Koyuki got out of high school, Mirio was able to show let his true self out and give Koyuki all his love and attention. Koyuki always had a hickey somewhere on his body because Mirio could be a little possessive at times, though Koyuki didn't mind.

Tamaki:
Tamaki is a shy bean and also a couple of years older than Koyuki. He waited till Koyuki was older to show more affection. Tamaki learned to be a little more open and less shy, with Koyuki's help of course. Tamaki loved holding hands with Koyuki in public, Koyuki just made Tamaki feel all warm and cuddly inside and he could help but show how much he appreciated Koyuki in his life.

Shinso:
Now, we all know Shinso loves pissing of Katsuki, so whenever he gets the opportunity, he is kissing Koyuki, tongue and all. Shinso likes to believe he only does this to piss the louder twin off, but in general, just loves kissing Koyuki.
Since Koyuki and Shinso have different classes, they can only see each other during lunch and after school. They make do with the time they have and try to be around each other as much as possible. Shinso can be a little shit at times, but Koyuki will tell him off and kiss him to make up.

Yo Shindo:
Luckily, Koyuki and Shindo were only a year apart but still didn't see each other until lunch. Shindo was nowhere near shy to show PDA in public but loved how flustered Koyuki could get. Kissing and groping Koyuki usually would get the most reaction. Katsuki was a little protective because Shindo was from a different school and did not know him that well, but slowly he got used to them, although he didn't like the fact that Shindo would literally grope his twin's ass if they went anywhere together.

Poly relationships:

Koyuki, Kirishima, and Sero:
Both Kiri and Sero loved showing PDA to Koyuki, who didn't mind. Katsuki was skeptical of him dating two guys(who were basically his best friends). Koyuki was slightly overwhelmed at first when the two both confessed that they wanted a poly with him, but he gradually got used to it and actually enjoyed being the center of attention for two men.

Koyuki, Mirio, and Tamaki:
The two third year's waited until Koyuki was 18 to initiated sexual actions, but besides that, Mirio was the one to consider both him and Tamaki dating Koyuki at the same time. Mirio was the dominant in the relationship, Tamaki was a switch, and Koyuki was the bottom, although Tamaki bottomed once for Koyuki on his 18th birthday. Now the couple didn't show too much PDA and Mirio respected both Tamaki and Koyuki's shyness. As far as they would go would be holding hands.

Koyuki, Todoroki, and Deku:
Deku was a little hesitant with how straightforward Todoroki was with Koyuki about dating the both of them. Todoroki didn't really understand or care for why people would stare at them if all three of them were to hold hands. Todoroki would be the top, surprisingly Deku would also be a top, and Koyuki would be the bottom. Katsuki went livid that Koyuki was dating his two greatest enemies, but realized that Koyuki was happy with the both of them and how much they both cared for him. Deku was hesitant to show PDA with Koyuki but Todorki did not give a single fuck.

Koyuki, Kirishima, and Tamaki:
Both Kirishima and Koyuki were both dating at the time. Tamaki told Koyuki his feelings for him and didn't expect to be excepted into a poly relationship with the both of them. Kiri was the top, Tamaki still being the switch bit preferred to top, and Koyuki as the bottom. Katsuki didn't really know how to feel with his best friend dating his twin, and then them adding a third party. Hiroshima loved showing PDA with his boyfriends, Koyuki didn't mind, and Tamaki was frightened at first but it took some time to come out of his shell.
