not a teacher
Laguna has a crush on Julia but he has been afraid to show it.
On this occasion, Julia comes up to him and says, "Would you like to talk somewhere private? I have a room here, I'll go ahead and wait for you. Ask for my room at the front desk, ok?"
Note my corrections. They are not necessarily the only possibilities for your text, but without further context I have just tried to make it more natural.
When his friends are wondering "Is he really going?", it probably means "Is he really going to Julia's room?".
