Chaewon hated your boyfriend.

She hated him even more for getting you pregnant and trying to force you to get rid of it at 2 weeks.

You were at her mansion as she tried comforting you in her bed, it was about midnight.

"He's not good for you" she insisted.

But you didn't seem to want to let him go as you believe he loved you.

But she had to make you realize that he didn't and the relationship was toxic.
