Fresh start? I call this a new season, like everyone's life. We climb mountains, then valleys, then mountains again. His talent can't be suppressed or silenced, and I am happy that a new agency will give him different opportunities to shine. I always think of Robert Downey (an American actor who rose from the ashes of public scrutiny) as becoming one of the best-known and admired actors in America. Yoo Ah In is beyond talented, and it is my hope that he obtains many lead roles that suit his talent and that we have a Korean Iron Man.

Is there actually a happy ending? The synopsis sounds pretty dark. ☹️
Yes and no. The husband divorces her for another woman, which turns out to be exactly what the female lead wanted. Husband kills his new wife "to preserve their love forever" but gets stopped by female lead before he can kill himself. The writer she used as a plot device in her marriage, finds out what she did (lured the woman intentionally into death), and he insists she turn herself in. In the end, we learn about what happened in the past, that everyone was a villain, husband goes to jail and female lead turns herself in with the writer besides her.
