[Which of these characters have the biggest impact in the drama?] 

1. 

I just got a call from Cambridge Police Station, they said that Seri has been pretending to be a student in Harvard University. They're suing Seri now, she has been sneaking into classes, goes in and out the cafeteria, and even lived in the student dormitory. Oh My God, she's insane.. She's totally crazy. She's afraid she may get caught that's why she flew to Korea. They asked compensation for 62,000 USD. I don't know what to do. What do we do with Seri, Seunghye-ya?

2.
