君にしか会いたくない。Grammatically correct?

[Leon1552]

Hi,

Is this grammatically correct?

君にしか会いたくない。

I don't want to meet anybody but you.

Also is this correct?

今回日本に来る主要な理由が君に会うんだ！

The main reason why I've come to Japan this time is to meet you!

or is this better?

君に会うために日本に来たんだ。

I came to Japan so I could meet you.

Which is more natural among natives? Sorry if it sounds cheesy XD

The last sentence is

君と初めて会った時から、ずっと考えてた。

I've been thinking about you ever since I first met you.

Are the sentences all grammatically correct?

Thank you.

Overall if you use them to your romantic relationship partner, you can use 君．
Otherwise, you should use people’s name.

君にしか会いたくない is correct.

今回日本に来た主要な理由は君に会うためだ！is a correct sentence.
However, if I were your partner, I wouldn’t like the word 主要な.
Of course you can have some reasons to go to Japan however, you don’t need to indicate other reasons to your partner.
I recommend you to say '今回日本に来た理由は君に会うためだ．’

君に会うために日本に来たんだ　is good.

君と初めて会った時から、ずっと考えてた is also grammatically correct.
