Hmm...The clouds are crying today. In this episode, Aya proceeds to flip another page from Chapter 18 to Chapter 19. Over the past year of being a pre-adult, she discovers a game-changer about life: adulting doesn't actually begin at 18th, it begins at 20th. With this, she starts her journey towards the "ghost age"—a commonly-used term for when you're not a minor anymore but you're not really an adult either. Watch how Aya introduces her new and improved mindset about BIRTHDAYS + character development from her 18 years of existence.
