[onf-headcanons]

ONF MEMBERS AS YOUR SIBLING (HYOJIN & E-TION version)

We will be heading to universe 3!!!!! (Still have a long way to complete this series as there are 21 pairing)

Either you are related from Hyojin or Changyoon side and either one of them later joined the family. Confusing? OK example you are Hyojin’s sibling by blood and then later Changyoon joined. Or in reversed, Hyojin was the one who joined later.

Or You are the youngest sibling (could be in terms age when the family comes together or you being born later)

Or, You are the eldest, as stand in for Hyojin’s elder sister, or Changyoon’s elder brother.

Any scenario that is suitable to your own imagination. Also there will be some repeated ideas from first universe because i would like to keep characterization consistency.

Btw this pair of sibling would be quiet but noisy unless they are triggered. But if you are their sibling, you might have already kinda used to the noise.

*For Hyo-tion, I will not be doing recommendation *winks

BUT!!! IT WILL BE FUN TO HAVE THIS DUO TO BE CLASSMATE TURNED SIBLINGS. To elaborate, Changyoon was transferred from Jeonju to Seoul some years ago, and then enrolled to the same high school/college class with Hyojin.

*ONE BONUS IDEA WHICH I AM NOT GOING TO ELABORATE, WOULD BE HYOJIN’S ELDER SIBLING AND CHANGYOON’S ELDER SIBLING GETTING MARRIED AND THEY BECOME IN-LAWS LOL 

Also, this family is close with the other 2 families that sharing the same universe. You can check masterlist to see which other families are in universe 3 here 

Ok lets go to some common headcanons (Also apply with you being the eldest)

They might need a bit of time, because suddenly they had to live in a household. Both are looking headstrong on the outside but also sensitive in nature.

(As food is important based on them both in recent interviews and Changyoon’s “we need to eat so that we could live.” ) THEIR USUAL GREETING TOWARDS EACH OTHER IS : “HAVE YOU EATEN?”

Frequently, non nonchalantly asking each other if wanna eat out

If you are related to Hyojin, should Changyoon finds a nice Jeonju cuisine restaurant, he would bring Hyojin and you over to try it out.

To elaborate it further, Changyoon will bring you and Hyojin around when the new family first visited Jeonju. It could be Hyojin suggested Changyoon to do that so that he can know more about his new brother. 

They act like being distant acquainted friends with siblings status recognised by the law, but actually both are very observant and caring towards each other.

You might worry if your brothers cannot get along well because they seems to be interacting less. But actually your worry is just overthinking.

Changyoon might be a bit intimidated by Hyojin because of his temper when Seungjoon teasing the latter. 

And Hyojin might felt Changyoon is a very distant person who prefers to be alone. But we all know Changyoon is just a bit timid when it comes to getting know/ approaching one step further with new people. So both are not a lone wolf type. With Hyojin being observant, he will absolutely stand back and let the other party to come when their more comfortable.

With INFP Changyoon and ISFJ Hyojin, It is not like they are not good at expressing sibling affection towards each other, they just don’t attach to the overly clingly brothers mode because they are more practical in my opinion. They tend to show each other they care by supporting each other, talking about deeper topics and remembering small details. 

Teasing and joking will be there (boys will be boys) but it is kept to the minimum.

(BTW depending on some sources Hyojin is ISFJ and ESFJ both are from some random variety show snippets, as from IDOL WORKSHOP where members mentioned Hyojin like to stay indoors, I will irresponsibly conclude him as ISFJ for now)

So it is possible that they will be awkwardly adjusting due to being too cautious until one party gives in and mentions they need to be more frank towards each other.

Then the chemistry start to change. Even though same age, Hyojin would act as if he is older than Changyoon.

Both knew about each other’s singing ability and will occasionally hang out at Karaoke. Bonus actually if they both have Youtube account that upload covers,you might suggest them to upload a cover video to Youtube. Also occasionally you are the one who suggested song titles for them to cover.

Then their subscribers might wonder how did they get close and as more collaborations happen, they just tell the truth.

If you are Changyoon’s sibling, you will help out by finishing his sentences when he is buffering. Hyojin knew about it as they are in the same class, he will give Changyoon some time to reorganize.

But then if they do fight, Hyojin surely will be the one blasting words, being on point as possible. (this scenario is rare unless it is something that triggered he to the point he could not hold in)

Even though they look “not close”, they will still laugh at each other’s jokes and weird antics. 

When they both are older, one of them had a notion to get a tattoo and started researching it and another gained interest after peaking. Then they both went to get tattoo together, Hyojin even get 2 because he could not decide. (Maybe later end up being scolded by parents lol)

Scenario  (You being the youngest or being the one to be born later)

Your elder brothers play with you by giving out a lot of weird aegyos. And then they will laugh at themselves for being OOC

BTW you three when playing hide and seek or tag in the house will defo turn the house up side down. 

From your childhood memory, Changyoon seems to be the brother who is smitten with you, typically likes to squish your chubby cheeks when you are still younger. Hyojin would be the sometimes prankster that would jumpscare you.

When you are toddler, Changyoon carries you in his arms most while Hyojin piggybacks you the most.

But both of their love are endless for the younger sibling. you might find it funny when you introduced your boyfriend/Partner to your brothers and Hyojin is the one who is being unsettled.

If you are from Hyojin’s side, similar with your brother, you might find Changyoon a bit intimidating. 

If you are from Changyoon’s side and you have opposite personality, you will be the one to approach Hyojin first.

BLESS your ears when they sing in the house.

RIP your ears when you play video games or monopoly with them both.

YOU FORCING THEM TO GO INTO HAUNTED HOUSES DURING THEME PARK VISIT BECAUSE YOU WON ROCK PAPER SCISSORS, and you are trying hard to catch your breathe as you laugh at your big brothers. Also RIP your ears.

OH AND RIP YOUR SOUL if you happen to messed up. Them both will nag you for sure. Changyoon is a more softer type big brother while Hyojin definitely is a more stern type. Changyoon forgives/lets go easily after he criticized and understood that you will learn from the mistake. But Hyojin will need you to understand what you have done wrong and exactly what led towards the mistake before letting you go free from his nagging.

So unlike previous sibling hcs, you will not go to only 1 brother when you ask for opinion/guides in life choices. You will come to them both same time. Even if 1 of them are not present, you will wait until them both are free and all ears.

They are supportive, but also worry if you are perfectly prepared of your choices.

Hearing them discussing in front of you before turn their opinion towards you actually can give you great insight too.  Hyojin will elaborate the consequences and makes sure that you understand and you have the mental preparation to bear it. Changyoon will be the worrywart and asking you some blindspot matter that you did not think of.

If your personality happens to be funny and a bit of crackhead underneath a serious facade, Changyoon will team up with you if you start something funny or you  joining Changyoon. Hyojin would be at one side clapping and laughing his heart out.

Changyoon : Woah, my younger sibling indeed, you sure have sense of humour

lol

If your personality is somewhat closer to Hyojin’s, you and Hyojin both will be supportive when Changyoon participating in singing competition.

Fun fact, should Changyoon participates, Hyojin will not participate. Same goes with the other way round.

Ok I am gonna stop here, I tried to add new hcs that I did not get to cross my mind during previous universes. You can read about them by searching Sibling!onf tag, or just refer to masterlist should you want to read more of Sibling Hyojin or Sibling Changyoon (but paired with other members)
