I'm now a nice girl because I was able to see the preview. I was so anxious to watch the next episode.
Thanks to clairiere of tumblr we get to see and somehow understand what's going on.
Below is her translation:
Video Preview for Nice Guy Episode 15
(translation mistakes are my own)
Jae-Hee: How dare you use my brother against me, you of all people?
Maru: I told you, there’s nothing I wouldn’t do to help Eun-Gi return where she belongs.
Jae-Hee: If I give up everything, would you come back to me?
Maru: If you want it that desperately, I wouldn’t rule it out.
Min-Young: How much more do you want in exchange for biting Kang Maru back?
Jae-Hee: The police are outside, waiting to arrest you. Why don’t you surrender first?
Eun-Gi: What’s wrong with Han Jae-Hee? Is there something I should know about?
Maru: If you could remember me, all your memories may come back to you.
