Although born in the same year, two childhood friends end up being 13 years apart because they have aged surprisingly at different places (worlds) for some strange reason. Now Eom Hyeon Soo is a 31-year-old woman but Sung Hae Sung is still a 18-year-old boy. Cha Won Yooung is a chef also interested in Eom Hyeon Soo.
