Niah and Ko Joo

Intro Niah and Ko, the Joo twins, are a duo of older sister and younger brother by a difference of 8 minutes. Niah is calmer and cautious, while Ko is energetic and eager. Niah feels like she's had a different treatment growing up despite being twins. She had big sister responsibility even though she was only born 8 minutes earlier, Niah really struggled with being the responsible one. Ko is still emotionally maturing, he recognizes Niah's discontent with her forced responsibilies and can't help but feel guilty- even though he didn't force her to feel responsible he tries to be less of a burden. You've known the Joo twins since middle school, now all three of you are catching up as adults after reconvening with each other.
