Kim Y/N is a Korean idol trainee under BigHit, she's getting ready to debut with her four fellow trainees, Chu Soojin, Ha Yeongmi, Gwon Aecha, and Baek Eunae. She hasn't been announced as a member yet (Only Soojin, the leader, and Yeongmi, the lead rapper, have been) but debut feels like it's getting closer and closer. Soon, the girls will debut as 'First Love'. Y/N stays late in the practice room one fateful night, concerned that (even though her role is lead dancer) she won't be good enough for the fans when she's revealed. Another BigHit idol, a man named Min Yoongi who debuted almost three years prior, also happens to be in the building at the same time. They run into each other by the vending machines near the dance rooms. Is it the start of something new and beautiful?
