For those interested, the Korean title has the word "오로지" at the start, meaning "solely/only." This is the girls name and it is extremely rare (government statistics say 48 people have this name, can't tell about it with the family name). The boy's name is 이기고, a conjugation of the verb "이기다", to win. This is referenced in the the 3rd page when he says "My name means victory". The government says only one person has that name, I hope they have the family name 이, cause that would be sick.
