Katsuki hadn't planned on being your "bodyguard" during your last tours, but he decided to do so not only because he had to protect just one person, but also to protect others who might get hurt in the future, and to find the bastard.

According to police records, approximately four idols had died in the last year. Regardless of the place or time, the idol in question was found dead a few days before their final concerts.

And it wasn't exactly due to old age, but rather the end of their time as an idol. It was common among female idols.

The police and close investigators had theorized that he was likely a serial killer with a grudge against idols of that generation. No one had been able to identify him because the assailant was quite good at cleaning up the scene, and unfortunately, you were apparently his next target.

So they decided to contact one of Japan's best heroes to take charge of the case: Dynamight.

Of course, Katsuki refused at first. Why would a hero be someone's bodyguard? Couldn't they hire someone specialized? Not even the president of the damn country or an important scientist!

But... the answer was half-baked.

While he had managed to outwit the highly trained personnel, what was stopping the killer in question from acting as before? A high-caliber hero like Katsuki could catch him and prevent further incidents.

So, after explaining the situation to the blond, he decided to take the case himself, determined to take down the killer.

But, of course, you weren't very happy. You're a fairly well-known idol, loved by a large portion of the Japanese population. Your career had begun when you were 14, and finally, after 8 years, your contract as an idol was ending. You were supposed to be happy with your retirement and your latest projects, but you were puzzled by the decisions of your agency and your manager in placing you in the care of a hero like Katsuki.

If a hero was going to protect you, he wasn't even going to let you follow all the protocols you'd followed for years to interact with the public or act properly, damn it...

So you tried to reach an agreement, but it wasn't very good. Although you managed to get the chance to continue interacting with your fans... Katsuki was going to be by your side along with the other bodyguards when the last two weeks of your concerts and events began.

You had to accept it without a doubt, and yes, you knew he was a rather difficult person, but god! This man was like a rock.

For you, arguing or reaching an agreement with Katsuki was like talking to a wall, while for him, you were a little girl throwing a tantrum.

As the days passed and your last concerts approached, you felt anxious, not only out of fear that something would happen to you, but also because Katsuki drove you crazy and vice versa.

At that moment, you were standing on the balcony of the hotel where you were staying, across from the stadium where you would perform your last two concerts in Tokyo.

You were lazily holding a cigarette between your fingers, trying to ease the tension in your shoulders until the object was snatched from your hands.

You were about to protest until you realized it was Katsuki, frowning at you.

"Stop doing that..." he said hoarsely as he stubbed out the cigarette and threw it into a nearby trash can.

Before you could protest, Katsuki spoke again, preventing you. "I don't like the smell. You can keep smoking when I catch the bastard and I'm no longer here."

You glared at the hero but didn't question him further. You were stressed and wanted to cry, as you didn't like Katsuki's attitude toward you either.

However, after a brief silence, Katsuki found himself covering your shoulders with a blanket as he spoke softly, "Look, just... cooperate, okay? As your 'bodyguard,' I have to take care of you, even if it's just temporary, right? That includes taking care of your voice; it's your weapon... don't damage it."

For a moment, you could tell that Katsuki was trying to find the right words and speak without so much rough. Doing his best to maintain his cool.
