None of his business

If Yoonmi had to describe Hyungsik, he was one of those characters who the readers felt pity for and wanted to be the male lead desperately. 

But then again, if he was the male lead, there would be some dissatisfaction; certainly, someone as devoted as Yoonmi over him, wouldn't be having such a problem.

The flaw with this man was that he was a complete psychopath. Although his psychopathic side didn't emerge fully right now, it was exposed further as the story proceeded.

Regardless of how disturbing or crazy someone found it, Yoonmi, on the other hand, fawned over it, finding it to be totally attractive. Although it was considered to be a flaw by the readers, she didn't exactly see it like that.

One thing, Yoonmi had to say was that Eunwoo was much more straightforward compared to Hyungsik. While it was easy to know with Eunwoo, who he hated and was fond of, it was a different matter with Hyungsik.
