Learn Japanese with Anime - It's Okay To Run Away

Analysis

嫌 (na-adjective) means “dislike” or “disagreeable” which is used to express your unpleasant feeling towards something. It’s a na-adjective so な follows it when modifying a noun.

And the noun is 時 meaning “time”. When it’s modified by a particular condition or situation, it works as the conjunction meaning “when” or “at the time at which …”.

So 嫌な時 means “at times you don’t like it”.

The は particle indicates the topic of the sentence.

The な particle is often used after a word or phrase in the middle of a sentence in casual male speech when convincing someone. And it’s often prolonged in colloquial speech.

逃げた is the ta-form of the verb 逃げる meaning “to run away”. A verb ta-form followed by っていい means “it’s okay even if one does something”, or “it’s okay to do something”. So 逃げたっていい means “it’s okay to run away”.

んだ is the combination of the broken version of the particle の and the declaring auxiliary verb だ. It’s often used when persuading someone.

The よ particle in the end of a sentence is used when telling something that the speaker thinks the listener should know so it’s often used when giving advice.

He could simply say 嫌な時は逃げたっていい meaning “At times you don’t like it, it’s okay to run away” which also makes sense but there’s no expression of persuading or giving advice to the listener. Adding these なぁ, んだ and よ makes the sentence more expressive and demonstrative.
