Kyung-Soo was angry as well as grateful to Jung-Hwa. More than angry, he was definitely grateful. Because of him, he was able to share a tender moment with Nivritti. She always used to run away from him but because of Jung-Hwa, she was locked with him.
He just wanted to see her every day. He had no idea that he would be able to see that to such an extent. She was standing before him without any clothes on her upper body. He never dreamed anything like that. It happened because of Jung-Hwa and to some extent because of Thae.
But he knew that Nivritti would be angry at Jung-Hwa for sure. He knowingly locked her inside with Kyung-Soo, and on top of that never forewarned her. She innocently was drying her clothes when Kyung-Soo barged in and saw her almost naked. She surely was going to kill him.
