Soobin: Hiyyih was quicker to greet me happy birthday than you.

Huening Kai: No, what? But at midnight I posted.

Soobin: Did you also greet me?

Huening Kai: Yes, I posted on Twitter.

Soobin: So what if you tweeted?

Huening Kai: Of course, it's to greet you happy birthday.

Soobin: That doesn't count since you must tell me personally!

After their funny conversation, Soobin brought up how Huening Bahiyyih texted him her wishes earlier than Huening Kai.

"She wished me happy birthday at 8 in the morning!"

Afterwards, Soobin mentioned a follow up text from Huening Bahiyyih, assessing if she had texted him earlier than her older brother to which Soobin hilariously agreed to.

"She sent another text that said, "I texted you before Kai oppa, didn't I?" And I replied, "Yeah, you're right. You're better than Kai."

The siblings have again made a memorable memory through their unparalleled chemistry, to which fans truly adore. It emphasized how close the siblings are, how TXT treats Huening Bahiyyih like their younger sister as well, and how much of a successful TXT fangirl she is.
