Analysis

好きにならないで

好き is the na-adjective meaning “likeable”, に is the target particle and ならない is the nai-form of the verb なる meaning “to become”.

Na-adjective such as 静か (quiet), 元気 (cheerful) and so on, followed by になる is used when the state becomes different so 静かになる means “to become quiet” and 元気になる means “to become cheerful”. And 好きになる is used when you start to like someone so it can be translated as “to fall in love”.

And a verb nai-form followed by で is used to ask someone not to do something in casual speech.

So 好きにならないで means “Don’t fall in love with me”.

もしそうなっても気のせいだよ

A verb te-form followed by も means “even if” and もし at the beginning of a sentence is used to emphasize that it’s based on the speaker’s hypothesis.

そう (adverb) is used to avoid repeating a phrase mentioned earlier which is in this case 好きに, and なって is the te-form of なる.

So もしそうなっても is equivalent to もし好きになっても meaning “even if you fall in love with me”.

気のせい (noun) literally means “because of mind” which can be translated as “one’s imagination” or “not real”.

だ (auxiliary verb) attached to a noun or na-adjective makes the statement affirmative and declarative.

よ (particle) is used to emphasize your opinion and make the listener aware of it. By using this particle, she is trying to make him believe that his feelings for her is not real.

So もしそうなっても気のせいだよ means “Even if you fall in love with me, it’s your imagination” or “Even if you think you have (fallen in love with me), it’s not real”.
