Quote from Lulu_Key

I keep forgetting that Ningning and Yuna are still babies

And it's weird knowing that Ningning and Tsuki shared the same age, while Yiren is two years older than them.

Also, Wonyoung and Hanni share the same year but Hanni looks like she shared the same year with Eunchae, Leeseo, Kyujin or Haruna. And still, Yiren is 4 years older than Wonyoung and Hanni.
