What is "Oh" in the Korean version?

[nleconte]

It's the verb ending ~네(요)

Thank you for that link! It is really helpful!

[avanade]

Oh dear = 저런! = 이런! = 오! = Good lord! = Good gracious! =Huh!

[kimmksk]

Oh itself can be written as '어머나,'

[sumnisumni]

Or you can just say 오!
(To be more casual, 앗! is also okay in this occasion.)

Weird! It marked "man's name" as a typo and put "man s name," but at least it did not count my answer as wrong.
