AV + (아/어/여 야) 되다
AV + (아/어/여 야) 하다
When we want to say should or must do something, we conjugate korean verbs by changing the verb into its present form (아/어/여) and adding ‘야 하다/되다’ to the end.
Whether the ending is 야 해요 or 야 돼요 doesn’t matter that much, they mean the same.
그를 봐야돼요! = You should see him!
운정해야해요. = You have to drive.
