Netizens are reacting with laughter and surprise from Nakyoung's Bubble chats with her fans about her sister.

On an online forum, netizens laughed over the tripleS' member's recent chat with her fans on Bubble about the recent 2023 Water Bomb events. She asked her fans what she should wear for the event and also mentioned that she will ask her real-life sister, the solo singer BIBI.

Nakyoung's messages to her fans:

"I wonder how my sister (BIBI) will dress"
"I should ask her"
"I'm sure she will try to dress like a hot girl again"

"Are you suggesting that I should wear twice as much as my sister's on myself?"
"How much is that?"
"I don't think my clothes will be that long even with that"

"My sister is gonna look like she is literally going to the swimming pool"
"You want me to wear a long padding!?"

"That would make me waddle"

"No, nope"

"I will show off my sexiness!"
