Wow I cried!!!!! Side A is the a story about a girl who cope up with her loneliness and problems with imagining NewJeans (her idol) as her bestfriends. At those moments, her crush is a constant reminder of how she cant escape reality forever. In side B, she 'drops' her 'friendship' with NewJeans and live in reality. Until one day when she's older, she opens the memory box and reminiscing her happy memories with NewJeans. She let them inside her life again with more grace and maturity, and NewJeans are more than happy to take it. :))
