I'm trying to incorporate as many 00 liners as possible, but only if I can write for their personality
His reaction to not knowing his girlfriend was related to a fellow idol
Aka, who your relative would be if you were dating him
(In age order)
Hyunjin "You have a brother?"
"Yeah, didn't I tell you?"
He shook his head no.
"Oh, well anyways, he's coming over in a few minutes to take me to the dentist"
"Oh, are you close?"
You shrugged.
"Kinda, we have a big age gap"
A few minutes later, the doorbell rang. You were in the bathroom, so Hyunjin went to open the door.
"Chanyeol sunbae nim?!"
He bowed and Chanyeol bowed back while laughing.
"Yeollie!"
You yelled from behind, running to give him a hug.
"Bye Hyunjin!"
You waved, as he stood there awestruck.
"Park Y/n, Park Chanyeol...I should have put that together sooner"
Renjun He knew you had a brother, because he first met you in the lobby of SM entertainment, and you told him you were there with family. You also spoke Chinese to him, and there weren't many other Chinese speaking idols in the company.
However, he didn't find out that Kun was your older brother until the NCT Christmas party, when Kun brought you with him.
"Everyone, meet my sister Qian Y/n"
Renjun was shook, but that didn't stop him from pursuing you.
Jeno The first time he met you, he thought you looked really familiar, but he couldn't put a finger on it. He didn't ask more about it until your first date though.
"Yknow, you look really familiar, are you sure I didn't know you before this?"
You shook your head and laughed.
"You probably know my sister, I'm a twin"
His eyes widened. Now he knew why you kept reminding him of ITZYs Yeji.
Baejin from CIX You've talked about your family before, so he knew you were close with your cousins. One day they invited you to hang out, and came to your house to pick you up. You let them in just as Jinyoung was walking out the kitchen.
"Chaeyeon? Chaeryeong? You guys are her cousins?"
The three of you nodded.
"Interesting, I can definitely see the resemblance"
Haechan I really had to think about how he would incorporate the definition of sass into this, but then I remembered he likes to tease people.
You were showing him a childhood picture of you and your brother, his hyung, Jaehyun.
"Are you sure you're not adopted? Clearly he got all the good genes"
"Are you calling me ugly?"
"Well yes, but actually no"
Jaemin Started laughing because he didn't believe you.
"Isn't Chen hyung too young to be your uncle?"
You had to explain biology and how family trees work.
"But if he's your uncle, and you're the same age as me...that means your mom had you when she was- OOOOOOOOOH I get it"
And you also had to call him for further proof.
Han Was surprised when he took you to an idol party with him, and you ran up to Dohyon from X1 (04 liner uwu), who happily accepted your hug.
"You two know each other?"
Dohyon nodded.
"Y/n is my aunt"
Que shook Jisung.

"What?! Y/n is too young to have a nephew!"
You had to explain that there was a very large age gap between you and your sister, so technically it was possible.
Felix Felix actually already knew that you were a twin, because the first time he saw you, you reminded him a lot of NCTs Jeno. Being Jenos twin made you older than him, but he didn't mind. He waited for you to tell him though, because he didn't want to annoy you, assuming you probably get that a lot.
Seungmin You were a new student in his class, and when you introduced yourself, he thought it was super cool that you were from Taiwan. Later when he asked you why you moved to Korea, you told him you were moving closer to family. When you started getting closer, he found out that your sister was Shuhua of (G) I-DLE.
Jongho As a BTS fanboy himself, he was shook to find out that Jhope was your older brother. He didn't want to seem like he was only dating you for that reason, so he wouldn't speak about it much. You knew how much he liked them, so you brought him with you whenever you went to see your brother. That would make him sooo happy.
And last but certainly not least:
Soobin When you told him that Heuningkai was your cousin, his reaction was "eww". But then it started making sense to him why you were even in Korea in the first place. He was annoyed because even though he was older, Heuningkai literally made him ask permission to date you. That didn't really interfere with much though.
This took me so long, geez. I didn't know that Jongho was so young, and then Soobin tall ass is younger than the dream 00 line, I-
