Is Seo Yeon testing that man by getting him married to another woman while she still wants him or what, I’m…
Yes she is trying to get full control over him by the fake marriage. I think she expected him to beg her to stay with him after realizing he can't live without her. That way she can have more leverage over him....as in she wants to be the one in control.
I noticed that too but i think it's cuz of her character . Like they are trying to portray her as someone who's alive but dead inside due to all the trauma she went though. I think her short hair is due to this too.
