Standard rules apply, but pinfalls and submissions only count when performed on her bed.

Jaegu was glad he had a training session with Momoi at her place before this, otherwise he'd be a complete mess right now, not knowing how to behave or what to do. He was still a mess, thought. This time there would be no privacy. He was told there would be cameras set up at Sakura's place.
This was also a way for LAW to save money as well as time for the main events in the arena. There were practically no expenses, other than to pay the participants and for the crew to set up the hidden cameras. Jaegu was not aware of that and was wondering why wouldn't they just have him fight in the arena? Though thousands of people watching live, really did a number on his nerves during his debut... But then again, this wasn't any better - In an apartment of a sweet and beautiful pop idol? Which raised another question for him - was she really a sweet person or was it just all an act for the public? He'll just have to find that out the hard way...
Finally, Jaegu approached the door and pressed the doorbell, waiting anxiously for the door to open.
H-hi there... I know it sounds strange, but... I'm supposed to be your opponent for tonight.
Jaegu would say once the door would open and he'd see Sakura. He would forget himself for a moment as his eyes would wander up and down Sakura's body with a blush before he'd remember that he didn't even introduce himself.
Oh! I'm Jaegu, by the way! Jaegu Song. He'd realise his blunder, but would try to offer a handshake. He wasn't sure if that was the right course of action, but he was too nervous to think straight.
