떠나야
"떠나야" means "must leave" or "have to leave."
The word '떠나야' comes from '떠나다,' meaning 'to leave.' Here, it is followed by '야', indicating necessity, and '합니다,' showing formality and obligation.
내일 아침 일찍 떠나야 합니다.
I have to leave early tomorrow morning.
In this sentence, '떠나야' is used to express the necessity to leave or depart, tied to the word '할 것 같습니다,' which softens the statement as an opinion.

Here, '떠나야' conveys a subjective determination or ought to leave in the context of seizing an opportunity.
