You were Takemichi’s sister—though no one knew that. Not even his closest friends like Mikey or Draken had any idea. For years, your identity had been kept quiet, mostly for your own safety and privacy. You looked to be the same age as Takemichi, which only made things more confusing for outsiders.

One sunny afternoon, you and your brother decided to spend some time together, casually strolling through the mall, laughing, teasing each other, and catching up on everything. It was a rare moment of peace in your lives, and you both cherished it.

But what neither of you realized was that a large group had been secretly tailing you the entire time.

Mikey, Draken, Chifuyu, Smiley, Angry, Baji, Mitsuya, Emma, and even Hinata had noticed the two of you from afar. Curiosity turned to suspicion as they followed at a distance, hidden behind shop displays and food court corners, watching every interaction with growing confusion.

"Who's she?" Mikey muttered, chewing on his taiyaki while narrowing his eyes.

“She looks close to him,” Chifuyu noted quietly.

“I’ve never seen him act like that with anyone but Hinata,” Draken added with a furrowed brow.

And Hinata—her heart clenched. The way you laughed, the way you touched his arm, how comfortable you looked walking beside him... it was eating her alive.

Finally, after spending hours together, you and Takemichi walked outside the mall. The sun had begun to dip low in the sky. Just before going your separate ways, you gave your brother a bright smile, leaned in, kissed his cheek, and pulled him into a warm hug.

But just as you turned to leave, a shocked and furious voice pierced the air.

“TAKEMICHI!!!”

Everyone turned. It was Hinata, storming toward you two like a hurricane, her eyes wide with betrayal and rage.

“What the hell is going on?!” she shouted, glaring between you and your very confused brother. “Are you cheating on me?! With her?!”

Takemichi’s face turned pale as the others froze behind Hinata, all of them slack-jawed and stunned, still trying to piece together what they had just witnessed.

You blinked in confusion, realizing the massive misunderstanding just as Takemichi raised his hands in panic.

“Wait—Hina! She’s my sister!!”
