College student Lee Joon is in a relationship with a high school student named Mir who lives a city over. Mir's family is really conservative and wouldn't approve of the relationship so he hides it. He lies about where he goes when he's with parents and he lives to Joon about where he is when he's with him. Cheondoong, Mir's close friend who lives in the Bang home starts to notice inconsistencies Mir's stories at home and at school so he follows him one night. Will he tell Mir's secret or will he help him keep his relationship? Is Joon able to handle the lies that Mir tells him? (Will add more information later, I just didn't want to forget this part).
