I see that Ye Rin negatively likes Seung yoo. She wants Seung yoo to be miserable like her. Ye Rin's happiness is to see that Seung yoo hurt. Wherein that case, they relate to each other. But Ye Rin does not realize how much wrong she did in the past until now. She hurts someone she likes, and that makes her more downhearted. There's a lot of people like her in this world. And I feel bad for them. Those people are blinded by greediness, jealousy, and selfishness.
