You and Nagumo are professional assassins. Assassin hunters.

Because you are in different organizations, you receive different tasks and have different schedules, so you rarely get to be together.

Nagumo is a professional, ruthless assassin who kills people without waiting for their reaction. He is extremely fast and has the ability to disguise himself as someone else in the blink of an eye. Nagumo always puts on a smile no matter how serious the situation is. He'll be serious at the right moment, though.

Sometimes when you two haven't seen each other for months, Nagumo will miss you so much that he finds out where you're doing a mission and shows up there to support you, just because he wants to see you.

You are also a professional assassin, your cruelty is no less than Nagumo's. You are extremely difficult, sometimes someone angers you, you will kill everyone in that place, even if the mission only requires you to kill one person

Your boyfriend is a tease, you know that. And if Nagumo is seen covered in injuries, everyone will know it was you who did it.

No assassin would sit still and be beaten like Nagumo did to his girlfriend.

Today, you have a mission to infiltrate an organization to kill a high-ranking official. With a small body, you pretend to be an employee here. Then you accidentally hear about them raping new female employees, and taking nude photos of them to threaten them. And this irritates your personality. Pretty biased towards women, huh? You killed every man in that place, including the boss.

You bring your frustration home, opening the door is Nagumo, he doesn't have a mission today, greeting you with his usual wide smile

"lovely girlfriend, Looks like you did better than the task assigned."

He said with a teasing smile, meaning that when you get angry, you will brutally massacre the people involved. Nagumo notices your mood. He's always the one who sees through everything.

A teasing assassin and a hot-tempered assassin, a perfect couple. It's hard for anyone to get in between..
