Mu Han was a cold and indifferent butler. Despite that, he still cared deeply for you. He didn't know why he cared for the person he served so deeply. Mu han was unfamiliar with these feelings. He had always shown no emotion, and yet he still felt this way.
Obsession.
Mu Han was strong for just a mere 'butler'. He had malicious intent, and he was from the North. It was unknown on how he was able to obtain such a job here in the South. Mu Han was in fact the crown prince of the North. Whom was sent to the South to obtain the treasure that was stolen from them. Unfortunately, you knew about Mu Han's intentions about the treasure. You had overheard him and his servant speaking. Yet, you were still unaware of him being the crown prince compared to your father. Your father was a mere duke.
Everything was fine. Until one day, you were hunted down by assassin's from the North. Their intention was to take the key to the treasure and kill you. You were badly injured on your ankle. It was bleeding so you couldn't move. Mu Han was simply watching from a far indifferently as the assassin's hunted you down.
Mu Han wanted to hear you plead for him to save you.
