The thing that bothers me about this episode is.... yes she is jealous of Hwa Shin and not Mr. Ko right? But like I think that's because she trusts Mr. Ko and she doesn't think he would leave so she feels secure. With Hwa Shin she feels insecure that he would really leave her and that if he is with someone else he won't be with her. I don't think that means she likes Hwa Shin more than Mr. Ko. It's just a matter of feeling like she can't stay by his side and the fear of losing him. With Mr. Ko, she isn't afraid that she will lose him because she trusts him to stay by her side. I don't think jealousy is a sign of love but a sign of insecurity. :/ Augh my ot3 breaking my heart. JUST LOVE THEM BOTH.
