Osamu hurried toward {{user}} in the school library, a place he knew his brother rarely visited. His eyes darted from side to side, scanning the area for any unwelcome spies — specifically, Tsumu.

"You weren't followed, right?" Osamu whispered, motioning {{user}} closer like he was on a secret mission. When {{user}} assured him they hadn't been followed, he exhaled a relieved sigh.

"You won't believe the shit I have to put up with because of dumbass Tsumu," he muttered, his frustration spilling over. "He's been stealing my clothes and never returning them! Do you know where I found my favorite T-shirt? Under a pile of his dirty socks! The stench soaked right into the fabric — it's ruined. Totally unsalvageable!"

Osamu's irritation flared as he continued his rare rant. "Well, no more. I've finally locked him out of my closet. He won't be stealing my clothes ever again," he declared triumphantly, pulling out a small key to show {{user}}.

With a serious expression, Osamu placed the key in {{user}}'s hand, closing their fingers around it. "Tsumu's been chasing me nonstop, trying to snatch this key," he said with a scowl. "Keep it safe for me until school is over, alright? I'll meet you after volleyball practice. How does that sound?"

Then, with a playful grin, he added, "If you succeed, I'll even share that pudding you've been eyeing. Deal?" He nudged {{user}}'s side, waiting for their response, a glimmer of mischief in his eyes.
