I sometimes forget to celebrate Chaeyu Day but today is a special day since it's literally their anniversary so I wanted to do something special.

Here is the ULTIMATE thread on why Chaeyu is THAT ship and why you should consider being part of the Chaeyu Cult:
They’re the maknaes. In Korean customs, age sets you apart from your peers as there needs to be a level of respect between the elders and youth. With Chaeng and Tzuyu, these expectations don’t exist. They’re literally on the same level.
They were classmates. Having Chaeyoung around greatly helped Tzuyu in finishing their schooling. Especially since Chaeng must’ve translated and guided Tzuyu’s way through high school.
When Tzuyu calls Chaeyoung "Chingu Chaengie" 😭đŸ„șđŸ˜©

Exhibit A:
Exhibit B:
Exhibit C:

Dahyun: [exists]
Tzuyu: Anyway, MY FRIEND CHAEYOUNG--

(I'm kidding Zeb 😂)
Their height difference. THEY’RE TOO ADORABLE. Tzuyu having to look down to talk to Chaeyoung, Chaeyoung have to crane her neck up to meet Tzuyu’s gaze.

(I would love to add more pictures but their height difference alone might take up half of this thread)
They’re the dimple line. You can see their deep dimples on either side of their cheeks—Chaeyoung on her right cheek, Tzuyu on her left.
They also poke each other's dimples.

Exhibit A:

Exhibit B:
They take cute selfies together.
It gets cuter when they add filters 😭

Exhibit C:
They just want to grow up faster (1) 😭đŸ„ș

Tzuyu has stated that she and Chaeyoung always spend time together which is why they're content on spending it in silence. (They ran out of topics to talk about wbk.)
Tzuyu chose Chaeyoung to be her girlfriend because she likes her. (This happened on December 11, 2015. Hence, Chaeyu Day.)
Chaeyoung has also said that she likes Tzuyu.
Chaeyoung also thinks Tzuyu likes her too much.

(She's so smug about it)
It was Tzuyu's idea to do PPAP but she didn't want to do it alone so Chaeyoung did it with her.
Chaeyoung refuses to do PPAP without Tzuyu because it would be boring.
When they sit next to each other on fansites and do cute shit like this:

Chaeyoung brings out Tzuyu's playful side.

Exhibit A:

Exhibit C:
Exhibit D:
Do you ever wanna cry about the way Chaeyoung hugs Tzuyu?
And the way Tzuyu backhugs Chaeyoung?

Exhibit A:
Exhibit B:
The subtle touches in little moments where they don't notice they're being filmed. Skinship is very important in Korean customs, especially when you're close with someone, and Chaeyu do it so naturally:

Exhibit A:
Exhibit B: Chaeyu at ISAC
Exhibit C: Chaeyoung's hands on Tzuyu's waist.
Exhibit D: Chaeyoung applying make-up on Tzuyu's face.
Exhibit E: Chaeyoung guiding Tzuyu, Tzuyu holding onto Chaeyoung's arm.
Exhibit F: Tzuyu running her hand down Chaeyoung's back.
Remember that moment when Tzuyu did aegyo and got so embarrassed by it? She saw Dahyun first but hugged Chaeyoung instead.
They're so CLINGY to each other. It's disgustingly cute.

Exhibit A:
Exhibit B:
Exhibit C:
Exhibit D:
Exhibit E:
Exhibit F:
Chaeyu shoulders: [exist]
Chaeyu: Ah yes. A place to rest my chin.
Remember that one time Chaeyoung borrowed a fansite's camera and took pictures of Tzuyu?
Chaeyoung loves to take pictures of her chingu.
Chaeyu: [minding their own business]
Chaeyu: MUST CHOKE
When Tzuyu looks at Chaeyoung instead of at the camera:
And the one time Chaeyoung looked at Tzuyu instead.
I had to insert this cause this was so fucking cute 😭😭😭
Chaeyu + Hearts = LOVE

(Chaeyoung drew that heart on Tzuyu's finger.)
Chaeyoung thinks of Tzuyu even when she's not there:

Chaeyoung: How tall are you?
Wonyoung: 169cm
Chaeyoung: Wow ... Tzuyu and ... (Similar)
Tzuyu looks for Chaeyoung when she's not around.
Chaeyoung CONSTANTLY praises Tzuyu.

Exhibit A: Body-wise
Exhibit B: Her figure
Exhibit C: PRETTY PRETTY PRETTY

(Also Chaeyoung instantly knew there was something different about Tzuyu's eye-make up.)
Exhibit D: Chaeyoung acknowledges Tzuyu's improvement on stage.
Exhibit E: Chaeyoung will literally not shut up about how pretty Tzuyu is.
Exhibit F: Chaeyoung slowing down just to flex Tzuyu's photocards.
Exhibit G: đŸ€·â€â™€ïž
Exhibit H:

"I don't grow any taller but she does. And she's getting prettier day by day. She's not only pretty but she sings and dances well."

(I'm fine. I'm fine. I'm fine.)
Tzuyu also showers Chaeyoung with compliments.

Exhibit A:
Exhibit B: Tzuyu is supportive of Chaeyoung's art. She posted a video of her chingu painting and Momo helping.

Exhibit C:

"Everyone is pretty but she's attractive."
Exhibit D: I'll just leave this here.
Exhibit E: A moment of Tzuyu admiring Chaeyoung's finger tattoos.

Exhibit F: Tzuyu literally clowned all the older unnies (except Mina and Dahyun) but called Chaeng cute. https://twitter.com/illiy009/status/794054323294633984
Chaeyoung thinks Tzuyu is the funniest member and always laughs the hardest when Tzuyu says or does something hilarious.

MC: I was really surprised ( when Tzuyu scored 4 consecutive 10s)
Tzuyu: Me too.
(The previous one is Exhibit A)

Exhibit B: Look at Chaeyoung clapping her hands like a seal.
Exhibit C: Chaeyoung says it so herself!
Tzuyu always proudly wears anything Chaeyu related.

Exhibit A: When Chaeyoung saw a fanmade sign that had the words "Only Have Eyes for Chaeyoung." She could've literally given it to anybody but she made Tzuyu wear it.

Exhibit B: Need I say more?
They feed each other.

(It's so gay.)

Exhibit C:
When they share umbrellas together đŸ„șđŸ„șđŸ„ș
Chaeyoung holding the cup of food and Tzuyu holding the umbrella for them đŸ„ș

Don't touch me 😭
One of my favorite things about Chaeyu is Chaeyoung's need to fix Tzuyu's hair or whatever she's wearing on top of her head, despite being so short she has to crane her neck up 😭

Exhibit A: Chaeng brushing Tzuyu's hair.
Exhibit B: Chaeng just ended up holding Tzuyu's fringe for her.
Exhibit C: This was so unexpectedly funny but cute at the same time.
Exhibit D: Plus points for them playing with each other and Tzuyu literally not letting go of Chaeng. But in the later part, Chaeyoung hands Tzuyu her flower crown back and wipes her nose for her 😭đŸ„ș
Exhibit E: Bonus points for this No Jam Bro moment.
Tzuyu makes fun of Chaeyoung's height.

Exhibit A:
Exhibit B: She literally CARRIED her oh my God.
Sure, she makes fun of it but—
We all know that if she could, Tzuyu would give up her height for Chaeyoung just to make her happy.

Chaeyoung: Tzuyu-ah, can't you give some height to me?

Tzuyu: YES! 👌
They have this thing between them where they just tilt each other's chin up. It's so adorable đŸ„ș😭

It's more or less Tzuyu who does it.
But there are a few moments where Chaeyoung does it too.
It's a Chaeyu thing.
"When two people have been together for a long time, they'll start acting like each other, not just with certain sayings or inside jokes but when they move, they'll start mirroring each other's body language."
CHAEYU BEING IN SYNC PLEASE 😭
The way they turned to each other đŸ„ș😭
The way they know each other so well 😭đŸ„ș
The letters they write for each other are always so genuine and heartfelt. The fact that Tzuyu noticed how easily Chaeng gets sick and how Chaeng is constantly amazed by how pure Tzuyu is—

I'M GOING TO JUMP OFF A CLIFF
REMEMBER THAT TIME IN TWICE PRIVATE LIFE WHERE CHAEYOUNG WROTE A LETTER TO TZUYU AND YOU COULD SEE HOW GRATEFUL TZUYU WAS EVEN THOUGH SHE COULDN'T PROPERLY SAY IT. DESPITE THIS, CHAEYOUNG UNDERSTOOD PLEASE THERE ARE LITERAL TEARS IN MY EYES 😭😭😭
THIS IS HOW TZUYU THANKED CHAEYOUNG FOR THE LETTER. SHE WASN'T ABLE TO SAY IT DURING THE MOMENT SO SHE MADE SURE TO MAKE UP FOR IT BY POSTING IT 😭😭😭
I'm just getting started with this thread. BUCKLE UP! Time for the really GOOD stuff! đŸ„°

Tzuyu flirting with Chaeyoung RIGHT TO HER FREAKING FACE.

Exhibit A: When Tzuyu wanted Chaeyoung to pick her.
Exhibit B: Tzuyu wrapping her arm around Chaeyoung and looking so SMUG about it. Dear God, this girl is possessive.
Exhibit C: Look at the wide smile on Tzuyu's face as she wraps her arm around Chaeyoung's and leans in to watch whatever it is that she's watching 😏
Exhibit D (1): Tzuyu literally telling Chaeyoung to say all of these things and Chaeyoung is just so DENSE OH MY GOD—
Exhibit D (2): SHE LOOKS SO HAPPY WHEN CHAENG SAID IT.
Exhibit E:

Chaeyoung: *calls another girl pretty*
Tzuyu: WHAT ABOUT ME?
Exhibit F:

Chaeyoung: h—
Tzuyu: WHAT ABOUT ME WHAT ABOUT ME WHAT ABOUT ME

Tzuyu 😭
Exhibit G:

Chaeyoung: [exists]
Tzuyu: CUTE
Exhibit H: Everybody knows Chaeng embodies a lion. They practically even call her Simba nowadays. So, do you honestly think that I'm going to look at this and NOT think that Tzuyu was flirting with Chaeyoung? Like she even GLANCED at Chaeng as she said it! 😭
Exhibit I:

THIS. FUCKING. MOMENT.

And when Tzuyu asked Chaeyoung where she wanted to go, the dense idiot replied with "waterpark" PLEASE I'M GOING TO RIP MY HAIR OUT
