Fake dating my idol enemy [ENG]

Lotta has been creating investigative videos about pop culture for years, but when she tears apart the K Pop industry and uses Hwang Hyunjin as her prime example, the internet explodes. He is furious, hurt, unforgiving - and determined to prove her wrong.

Just as Christmas begins to creep closer,
Lotta slips into an even bigger mess: in a moment of pure desperation she told her mother she finally had a boyfriend. Hugo. Does not exist. But needs to... at the latest four weeks from now, under the Christmas tree.

Then Hyunjin stumbles across her anonymous cry for help in a Seoul community forum - and offers her a deal that turns her entire life upside down:

He plays her fake boyfriend for Hamburg.
In return she has to vlog with him for four weeks, give him a fair chance, and get to know him as a person... no sniper questions, no razor sharp analyses. Just him. Just her.

Problem:
They are fire and gasoline.
He impulsive, she stubborn.
Verbal battles worthy of the Hall of Fame.
Chemistry neither of them is ready to admit.
And vlogs that send half the internet into meltdown.

What happens when you start to see the human behind the enemy?
And what if the fake boyfriend suddenly feels a lot less fake than planned?
