Ooo I was thinking it might be Chaha (Cha from Chayoung and Ha from Gyuha)
I was thinking that possibility too, but chaha doesn't sound natural for me (just my opinion lol), then I thought maybe (gyu)HA (cha)YOUNG. So his name is still an abbreviation of both of her parents (⌒▽⌒)
*his parents
Yeah that makes sense! Excited to know what they (the author really) decide to go with, could also be something completely different
Will the second child be named Hayoung? Since the first one is given a name with an abbreviation of gyuha and chayoung, so the second child might be the same haha ヾ(☆▽☆)
