Hi,

Don't worry! I am aware that the girl who will come here tomorrow is your girlfriend.

Which one is more proper to use according to you? Must we use 'to' or 'ing' when using 'will' in sentence?

1.
Don't worry! I am aware that the girl coming here tomorrow is your girlfriend.
2. Don't worry! I am aware that the girl to come here tomorrow is your girlfriend.

Thanks.
