it definitely made me question myself at first too.
her name is the same but it was previously spelled Yeon (now Yun) and when her father calls her name endearingly it becomes Yeon-ah (Yun-ah/Yuna) or Yeon-ie (Yuni).
idk why they changed the spelling. i preferred the previous one because it’s easier to distinguish between the [eo] and [oo] sounds for names spelled with "U" e.g. they spelled her name YUN but it’s actually pronounced [Yeon] and not [Yoon]—those are two different names
Oh I see. Thank you for the explanation! I initially thought it was a completely different name, haha (^o^;)
did her name change?
