A picture of a yellow lab (Jumin's representative animal) and a white cat (Mason's representative animal) peeking over a ledge together. The yellow lab is wearing sunglasses and the cat is squished up against the lab with a big smile and hearts to the side. Below the animals is the text "Happy 10 Years!" and to the side of the animals is each idol's respective signature.

Happy 10 years anniversary to jumason! From their reunion when mason came to Korea, to them achieving new heights together and having each other’s back no matter what, their friendship is of the purest and most beautiful kind 🤍

Mason is taking it home 100%
It's the dorm cat now
You cannot tell them to let it go
They will cry
Let them have their new cat

I'm pretty sure I have co-ownership of Felix, Taeho, and Jimin at this point 😂 I'm always having Cas interact with them (ofc Felix and Mags have co-ownership of Cas too)

I think my favorite thing about the dynamics is just how well they play off each other and how chaotic they can be

#OCCasChen

Randomly thinking about how Mason's first language (Chinese), native language (English), and primary language (Korean) are all different lmao

#OCCasChen

Salmon. Pac(t)man. Simeon's boyfriend. The guy who's the reason their OM canon stopped at season 2.

It's probably not even mutual disdain but they're enemies and rivals for sure.

#OCCasChen

Mason really, really wants to perform a rock song with a band. And learn guitar because some of their friends play and they think it looks cool.

#OCCasChen

Mason is a gender enigma. While they will use masculine terms and dress in a more masculine manner as part of a boy band, their appearance is best described as "pretty" or "cute". Off the clock they avoid gendered terms and keep a very neutral fashion. No one knows their actual gender.

#OCCasChen

Because they are impulsive and have a pure personality, I think that the fandom would definitely baby Cas and treat them like they're air-headed and so innocent that they need to be protected at all costs. But they are a fully grown adult who can very much take care of themselves.

#OCCasChen

Mason gets homesick from time to time, but it was especially bad when they first came to Korea. Not having their family around in a new country where they didn't know the language made it hard for them to adjust and they frequently missed the life they left behind.

A picture in the style of a playing card by angelkissedface. The card is a joker with mirrored images of Mason (aka Cas) and August on either side. This orientation has Cas' profile featured upright. They are smiling happily with their eyes closed, back to the viewer, and wearing their signature white jacket, choker, and a small bell earring. Cas is framed by white lilies and a white cat on a blue background with the word "Joker" running down the side in gold. Please see the additional image for description of August.

This orientation has August's profile featured upright. They are smiling lightly with their eyes open, back to the viewer, and wearing their favorite red and white varsity jacket. They also have two red barrettes in their hair. August is framed by red roses and a black cat on a red background with the word "Joker" running down the side in gold. Please see the additional image for description of Mason, aka Cas.

"The fun thing about a joker is that it can become any card in the deck~"

For the first art of the new year, I want to show off my BEAUTIFUL commission from @angelkissedface.bsky.social, featuring my favorite mischievous kitties, Mason (aka Cas) and August 🐈🐈‍⬛

End of the year music festival, celebratory live with the rest of the group, crashing for the next 12 hours in that order 😂😂

#OCCasChen

Quick reference guide for Mason Chen, also known by their stage name, Cas. Mason is a non-binary individual of androgynous appearance. They have fluffy, blonde hair that reaches the base of their neck, loosely resembling a kpop mullet. They are wearing a dark blue hoodie with a yellow stripe in the middle, a white jean jacket with a yellow stripe down the side, blue jeans, and red converse. The left side of the page has details about their design and thier signature, and the right side has their color palette. Below the color palette is a close-up of their right hand showing their black and white rings and their left ear, showing their 6 piercings.

To celebrate the end of 2025 and their 5-year anniversary, I made a new quick reference sheet of my favorite OC with their updated design. They've come a long way since 2020, thank you to everyone who's been with them on their journey. 🫶🏼

On the flip side, I think that they would ask for camera or gaming supplies for themselves. They would really love to spend Christmas with their family as a gift, but it just isn't possible yet. Maybe someday.

#OCCasChen

A portrait of Cas, dressed as a Korean reaper or demon (but not entirely accurate). There is a significant amount of negative black space, which is used to imply the missing parts of the piece, such as the hair and the gat.

This isn't what you think it is... 💦
...Or is it? 😈💀

#New_DayOCs #OCCasChen

멋쟁이 그대가 사뿐히 걸어가면
무서운 고양이 뒤따라와요
달콤한 꼬임에 속아서 간다면
후회를 한다해도 나는 몰라요

Are you ready for a scare? 🤍

#OCCasChen #New_DayOCs

You cannot convince me that Cas would not have a cake like this at some point ><

#OCCasChen

For Mason, it's easily the day that they passed the audition to become an idol or the day they officially debuted with their members 🥹

#OCCasChen

As August comes to a close, thank you to everyone who made this a happy month and for celebrating my beloved Kitty Cas with me! I hope September is kind to you as well. 🫶🏼🤍🐱

A picture of my OC Mason (Cas) wearing a black hanbok and gat, emulating a grim reaper. They are smiling with their natural fangs showing and making a cat ear pose. Their eyes are nearly covered by their golden yellow heterochromia, which is usually only seen as a sliver at the bottom of their iris. Their face is framed by black smoke.

This isn't what you think it is... 💦😈

Merry Christmas with a bonus sketch!!! 🎄🎁☃️✨

Idol OC Cas sits against a wall holding a stuffed polar bear. They are wearing a knit sweater and have star stickers on their cheeks. Red ribbons hang above them. In the bottom left corner is Korean filler text, suggesting that this is an imitation of a page from a magazine photoshoot.

Merry Christmas!!! 🎄🎁☃️✨

OCs Cas (Mason) and Kkun (Yongsoo) in winter coats laughing together as snow is falling around them. The piece is inspired by idols' First Snow challenges in 2023.

Saw this on another app and it made me think about Cas and how, at the end of my rp days, I wrote a lyrical piece about OM!Cas just crashing and falling apart from the weight of everything

And then I made NEW_DAY for them to shine 🥺
