"Should I play the recorded voice for him now? I hurriedly searched through the archive in my head. What do I have to play for him?
Then I remembered the last voice I recorded, and suddenly my vision went white.
'Ah...! Uh, yes! It's, good...!'
If I play this, wouldn't I just be a pervert asking him to listen to his own moans?
Then what should I play?
Our phone calls? Cha Gweonwoo telling me he loves me? Me cursing, 'Wake up, you idiot Cha Gweonwoo'?

But you know what.
The momentarily bubbling motivation disappeared like foam, and suddenly this sense of skepticism hit me.
What would change even if I played it for this guy?"
WTF!!! I thought he was a gentleman. Such
big ahole! What a turn off!
Yeah looking at how he acts I definitely knew he would be like this LOL. He’s possessive and extremely violent.. very fitting.
