Lee Cho Hee is an average high school student who grew up from different countries. Cho Hee was born in China but both of her parents are korean. Her parents met each other in china when they were still in their 20's. Both of them decided to get married and that's when they got their first child, Cho Hee. After 12 years of living in china, her dad was promoted and had to go to America, Hawaii to be exact, to continue working as a bussiness manager. Both of her parents, her and her younger brother, Chad (10) went to America and live there for 4 years until they decided to go back to Korea just in time for her high school year as a junior to start. Can she make a lot of memories, despite having only 2 years instead of 4years of being in that school? Can she fulfill her bucket list of what she calls"High School Memories".

 Luhan is  also an incoming junior student. He's a part of the school gang called Exo M, the full package group, in what they are known for because one they're  rich, second they're smart and lastly they're all good looking. Behind those word, all the members came from broken families. All of them share similar life story and that's maybe because they fit with each other well. Of course the school doesn't know their stories since they don't  want them to know except for some students who really knows them. Luhan is a very arrogant,  can sometimes  be mean but when he's with his love ones his actually a sweet loving guy, especially to his mother, who works hard to give everything Luhan need.

 Lee Chad, your brother 2 years younger than you, incoming freshman and entering the same high school your going. He's very arrogant kid and likes to tease and irriitate you purposely. But deep inside him he loves you and cares for his sister, you.
