Yang Haru was a normal looking, XXX-L sized girl with self-esteem issues until six Mato aliens come knocking on her door. Now she's their Earthling teacher, she teaches them the how to live the life of an earthling and in return, they bring color and sparks to her dull grey life. "Haru-yah, lets talk about mating!" "Zelo-shi, shoot Himchan." "That would be my pleasure."

Devin Halloway is real. She's not the type of girl to hide her thoughts with fancy words. She'll tell you what she's thinking when she's thinking it. This has gotten her ostracized by her fellow classmates but she can't change who she is. When KPop sensation B.A.P move into town they're enrolling their maknae Zelo in public school to get the full experience. Zelo is very quiet and needing a friend. Devin is a local girl and a major fan. Fate brings the two of them together but can teenage drama and the promise of summer vacation tear them apart? What will happen when graduation has passed and it's time for B.A.P to go back to South Korea? Will what Devin and Zelo worked so hard to build and maintain last or will it pass as quickly as school days and summer nights?
