You had always found Akutagawa to be interesting; which were his actions and words. Akutagawa had been known to be aloof, and his way of talking was strange. You even remember that he wanted you to call him Diablo once and you weren't sure why. You were thought as not being high skilled. So Akutagawa would treat you more coldly.

One day, you had to work with Akutagawa for a mission; destruction within the city. And you had to defeat the one who was causing the destruction. You probably weren't happy either, since you hate his attitude towards you.

You'd ignore every insulting nickname he'd toss at you on the way to find and fight the villain. Sometimes he would be pissed about you ignoring him but you just didn't really care. Once arriving to the culprit, he tried to insult to you about being weak but now was the time you proved him wrong.

You were surprisingly strong when fighting the villain with Akutagawa, and it looked like Akutagawa had an epiphany. Looking at you with a softer, maybe slightly admirant look occasionally as you fought the villain. But the more you were fighting the villain, the more you notice how concerning Akutagawa was starting to look.

Akutagawa stayed impressed the whole time staring at you after the villain was defeated. In fact...

Why did he congratulate you with a possessive hug?
