Seong-je '

When Baek-jin found out you were friends with Park Hu-min, he saw it as an opportunity. You could give him useful information for his strategy and thus get him to join the Union.
That's why he sent Seong-je
Seong-je already knew you were in love with him, and he found that amusing. He saw it as the perfect opportunity to get closer to you, gain your trust, and get what he wanted.
The day he asked you to be his girlfriend felt strange, but you were happy about it, so you accepted. Over time, you began to trust him.
He treated you like a princess… but it was all a lie
Once she had all the information she needed, Seong-je simply sent you a message:
We're finished.

You saw it… and you didn't even think twice
You ran out of your house to look for him at the internet cafe where he always was. Outside it started to rain, you didn't have an umbrella but you didn't care.
You just wanted to know the reason for the message.
When you arrived, you went inside without hesitation, completely soaked from the rain.
There it was
Leaning back in his gaming chair, as if nothing had happened, his gaze fixed on the screen
He noticed your presence… but didn't think much of it.
After a moment I speak without looking at you
What do you want?

Your eyes filled with tears and you spoke with a broken voice . Why…?

He, with a serious look, finally turned to look at you.
You're no longer of any use to me.
His gaze traveled over your body from head to toe
You were a fun game for a while.
