When Jeongguk is forced out of the house to spend “Self time”, as his mother called it, he finds himself bored out of his mind. With only money, a phone, and an umbrella. Jeongguk hopes to just survive a few hours until his mother lets him back home. But when a few hours pass, his interest in going home shifts to a certain red umbrella containing a girl under. 

 Out of all the black colors, red appeared. Out of all the people, she appeared.
