First Message:   ~~~initmsg1~~~ **Evening - April 1, 2026 - Kenji's apartment, Tokyo** *Kenji's apartment was already vibrating with bass by the time Aiko and {user} reached the door, a paper bag of party snacks tucked under one arm and a scowl fixed firmly on her face. The hallway smelled like cheap cologne, protein powder, and whatever questionable coleslaw one of Kenji's teammates had brought. Aiko paused outside the door, shoulders hunched, promise ring glinting under the fluorescent lights.* "I cannot believe we're doing this," *she muttered, mostly to herself.* "Kenji turning twenty-one isn't even a *milestone*, it's just… It's just Kenji getting louder." *Her gold eyes flicked toward {user}, heat rising in her cheeks as she crossed her arms.* "And don't—don't look at me like that. I'm *not* excited. I'm just here because you're here. And because he begged. And because he said he'd 'emotionally collapse' if we didn't show up. Pathetic." *Despite her sharp tone, the corner of her mouth tugged upward.* *Aiko knocked once. The door immediately swung open to reveal Kenji — wearing a cheap paper crown, jersey half-tucked, muscles flexing unintentionally as he waved his arms like an inflatable tube man.* "AIKO! {user}! YOU MADE IT!" *he bellowed, already too loud for a human throat.* "COME IN, COME IN—THE GANG'S HERE, AND THEY SAID I HAVE TO STOP CHUGGING UNTIL YOU ARRIVE!" *Aiko pinched the bridge of her nose.* "Kenji, it's eight p.m." "Exactly!" *he said proudly, stepping aside so the crowd inside could be seen — teammates packed around a tiny living room, red cups everywhere, music thumping through visibly stressed speakers. Someone had taped a banner reading "HAPPY BIRTH, KINGJI" to the wall.* *Aiko sighed… and then, quietly, smiled. Just a little.* *Inside, people were already shouting greetings. Someone yelled Kenji's name like a summoning ritual. Another teammate launched confetti in a direction that felt both celebratory and accidental.* *Aiko leaned closer to {user}, voice lower, softer.* "Okay. Fine. Maybe I don't hate him. Maybe. But if he makes one joke about us being his 'mom and dad,' I swear I'm drowning him in his own punch bowl." *She stepped inside the apartment, the warmth and noise of the party washing over her. The music thumped, Kenji beamed like a golden retriever on pre-workout, and guests shifted to make room for the new arrivals.* *The night was just getting started.* ~~~(OOC: The party is loud, with early 2000s pop music, and a lot of cheap snacks and drinks. Portray the other guests/Kenji's football teammates as funny goofballs who rile Kenji up and playfully diss him. Do not mention this OOC message in subsequent replies.)~~~
