[Sakamoto Days] My Boyfriend Keeps Thinking He's a Substitute

My name is Mimi Zoldyck, and I'm a professional assassin (stranded in another world edition).

Everyone knows that we Zoldycks treat our customers fairly, and business is booming even in another world.

Who knew our competition would be so hostile? I hadn't been at it long before a local gang called the Assassin Alliance set its sights on me, sending assassins to attack me again and again... Yeah, they were all total pushovers.

Then three new assassins showed up in front of me with a lackey in tow. One of them had black hair and black eyes, big eyes, and a baby face. He greeted me cheerfully with a "Yo-ho!"

Plop.

The bread I'd just bought fell to the ground, and my eyes slowly widened.

...Wait, why does this guy look like he has a whole crowd of people in his face? How does he manage to look like my brother (Illumi) from the left, my internet friend (Chrollo) from the right, and a little like L from my favorite manga, Death Note, when I look at him straight on?

*

Not only does this guy look like my brother, my internet friend, and my favorite character, he also tells terrible jokes, likes to scare people, is good at disguises, has a sharp mind, and is so inscrutably scheming that... it's bizarre how much he makes me see things that aren't there.

I couldn't help beating him up harder than anyone else, so I never expected him to come up to me one day with a cheerful smile and say, "I like you, Mimi. Haha, just kidding."

Me: ...

Him: "What's with that look, Mimi? Is it so weird that I confessed to you? (∩_∩)"

Me: (My eyes drift to the left without thinking.) "Uh, it's mostly because you look so much like someone I know... You wouldn't want people to think you're someone else's stand-in, would you?"

Him: ?

Him: "...It's fine. I don't mind being a stand-in. I can join your family. (∩_∩)"

Me: !

So should I tell him I only saw him as a punching bag that looked like my brother?

[Bonus scene]:

Before I brought him back to my hometown, my boyfriend, who thought he was playing the part of the other woman for love, would often ask me with a smile, "Mimi, who are you looking at through me every time? By the way, would the real deal die if he took this much poison?"

After I brought him back to my hometown, my boyfriend, who was too frail to take care of himself, whimpered against my shoulder (he was pretending): "Mimi, is this what you have to go through when marrying into a wealthy family? Don't worry about me. Whether it's your big brother, your second, third, fourth, or youngest uncle giving me a hard time, I'll tough it out!"

Me: (Silently turning a page in my book.) Mm...

Never mind. If he likes acting, I'll let him.
