Obsession

The male lead is a crazy, extremely jealous king. The female lead is setting up a plan to escape her faith-death. She reincarnated as someone from Korea to a novel world.

Unforgotten teen romance that wasn't even started because the male lead needs to hide , again. After few years the FL had gotten successful and the second male lead stayed with her. t's the 2nd male lead who's obsessed with the female lead since senior high. I just got the 'second male lead syndrome' here.
