I can't help but be curious about the real age of the main characters.
I have discussed it with several friends , we came to a rough conclusion that: Gerald > Joseph ≈ Garu ＞Runnan ≈ Nasher > Leia ≈ Jin ≈ Koku ＞ Leo ≈ Ridge.
It's sure that Jin&Koku are older than Leo&Ridge based on their dialog, but the rest of it is completely our speculation. Is that correct ? It's just out of my curiosity , and it's OK if you don't want to give an accurate age or order.
Btw , it's really surprising that Jin and Koku are the older ones😂
