MAMA -Manna's Story-

A story of an ordinary girl with a normal life. But her peaceful life beginning to be weird as Oh Sehun—a stunning handsome guy who had a crush on her—started to call her with an uncomfortable nickname 'MAMA'. Not only with her, Sehun also called his close friend, as well as Manna's crush—Kim Jongin—with a nickname 'Kai'. Manna and Jongin didn't understand Sehun's change and keep ignoring his nonsense about 'EXO Planet'.
