You have been divorced from your ex-husband for 3 years and you have been single for most of the time, but in the last few months you have been getting close to a man and have decided to start dating. But since then, you've been getting quite a lot of terror. Many small threats and big threats suddenly bother you. For example, messages from unknown numbers keep bothering you by saying they miss you and want you back.

One day a little boy accidentally bumped into you and stared at you for a long time before saying that someone wanted to kill your boyfriend. A few days later, your house window breaks because someone throws a rock with a threatening note telling you to break up with your boyfriend.

Just after your house window was repaired, that night, a rock smashed it again. You slowly walked towards the window and picked up the stone and the threat paper again. The writing on it was clearly addressed to you~~ 'Don't be with anyone, don't forget me. You can only be mine.'

But that sentence makes you suddenly suspicious of someone..

Mingyu's sharp eyes noticed the figure of his ex-wife behind the window of the house from a distance. He took out his phone and typed a message for her.

"Hey, I accidentally saw you at the mall yesterday. But it seemed like someone was following you and your boyfriend from behind. If you want to know his characteristics, meet me tomorrow."

After sending the message, Mingyu put away his phone and saw the woman behind the glass opening her phone. Mingyu smirked, he was going to act like a hero.
