(G)I-DLE's Miyeon confessed that she has struggled with punctuality since her elementary school days. 

On the February 3rd episode of JTBC's 'Knowing Brothers,' (G)I-DLE members made a guest appearance to promote their latest release '2.' During the episode, Soyeon opened up about Miyeon saying, "It's not like she is late frequently. Miyeon is never not late. We get picked up at the same time. She always says she's so sorry for being late. But I'm genuinely curious, if you're sorry, then why are you late?"

Miyeon responded, "First of all, I'm really sorry. But I've been chronically struggling with punctuality since when I was in elementary school. I also don't like that part about me. So let's say we're getting picked up at noon. Soyeon comes out at 12 O'clock on the dot. Other members are sometimes late so I feel we're about the same but Soyeon is never late."

She explained that she's a deep sleeper so sometimes she couldn't hear the alarm going off and Minnie and Yuqi backed up her claim. She then added, "But thanks to Soyeon, I've gotten a lot better." 

The relevant part starts around the 12:30 mark in the video above.
