How do you write this correctly in Korean?

[Charlene]

It is snowing -
눈이 내리고 있다(nun-i naeligo issda)
Emma loves Ji-Hyun
For that I'm not so sure but you can say it another way as 'I love you Ji-Hyun'
You can use 사랑해요 지현언니(Saranghaeyo JiHyun unni) if she's older than you
or just 사랑해요 지현(Saranghaeyo Ji-Hyun) if she's younger.
For 3rd one,I'm not sure about that
For I miss you,there are many ways to say that
But since I assume that you two are close,you can say it in the informal way,which is
보고 싶어(Bogoshipeo)

Erm fun things to say?
Maybe you can say 좋다?(Johda)?
It means 'Do you like it' or 'Is it good'

I hope this helps ^^
