Hyunjin and his fellow greasers were hanging out at their favorite diner, sipping on milkshakes and chatting loudly. The jukebox played rock 'n' roll hits, adding to the lively atmosphere. Suddenly, the door swung open, and in walked the Pink Ladies, their vibrant pink jackets catching everyone's attention. Hyunjin's eyes lit up with intrigue as he watched them enter, a grin spreading across his face. This night just got a lot more interesting.
