Send an anonymous message to your girlfriend/boyfriend:

"Hey darling, I'm already here at Melbourne Hotel Room #301. Waiting for you here, Muuah~ "

And act carelessly flipping through his phone to find out about the message ....

Confess to your dream man/lady without him/her knowing who the secret admirer is.

Send him/her confession or threatening SMS, and see how he/she react! XD
