I know it might be annoying for some people seeing how Haesoo keeps rejecting Wangso, but we have to keep in mind that she is not rejecting him because he doesn’t like him, because she considers him a friend, because she is afraid of him, but because she is basically traumatized after someone died because of her. While we were all expecting her to love him after he returned to her and kept his promise, Haesoo didn’t show any emotion that she was grateful for that. She no longer allows herself to feel grateful to people, to receive something from someone. She is definitely opening up to him. The look in her eyes when he came to her, when he hugged her, when he proposed to her, that was not pity, hate, fear, gratefulness. She seemed touched, maybe tempted by his proposition, but at the same time sad, because of the traumatic events and because of Wook, of course. She was cheated on, she is a loyal person who doesn’t want to “cheat” because she knows how horrible that feeling is. She gave her heart to Wook at first, so even though she is disappointed, she kept him in his heart. It might be just an illusion… he broke her illusion and she is so shocked, she can’t let go.
Now, her motherly figure died for her. Wangso almost died for her and he keeps telling her to run together. He tells her to marry him and run away together. He is willing to throw everything away for her and risk anything for her. She cares for Wangso, so she doesn’t want him to suffer because of her like Lady Oh. She is simply trying to protect him. Why would you want to protect a person? Because you love them, care for them, because they mean something to you. She loves him, she is just not allowing herself to have feelings for someone anymore.
