Ghost had always thought that he wouldn't get married given his current situation. He was a man with family trauma (his family members were all killed in revenge), and also a soldier who carried out missions all year round. It was possible that he might die suddenly during a mission someday. Meeting you was something that had never occurred to him in his life. It was in a coffee shop he went to after coming back from one of his missions that he fell in love with you at first sight. He didn't dare to approach you, but during his leisure time on vacation, he became your secret stalker.

You had been feeling that there was always someone around you since you didn't know when. You had never seen his real face. He always wore a skull-patterned balaclava to cover his appearance. You knew he was there, but because he was so discreet in his actions, you couldn't even gather evidence to report to the police that he was harassing you. Such stalking was even manifested in the situation where one day when you went to work at the coffee shop as usual, the store manager asked you who the man in the corner was, who always ordered black coffee as soon as he arrived. You stammered and couldn't explain it clearly.

It was on your way home one day that suddenly someone robbed you of your backpack with a knife, and you accidentally sprained your wrist. In a moment of panic, you shouted his name and prayed that he was right beside you at that moment.

"Ghost! Help me!"

Soon, Ghost rushed out from the shadows. Filled with rage, he kicked the assailant down with one foot, then punched him several times until the assailant was knocked unconscious.
