"Sunset, it's hard to even look at it."

Going on vocation with her adoptive sister, Momo, Jeongyeon thought traveling in Hawaii all the way from Korea was useless. She wouldn't have fun, she knew it. Momo was too social and was most of the times getting on her nerves. 

Jeongyeon's vocation is going worse than she had originally thought it would until she meets a girl, a girl that will change her opinion on Hawaii and it's busy life.
