Years ago, a wealthy conglomerate family was worried after having six daughters in a row. However, exactly a few months later, around December, a son was born. His parents were overjoyed and named him Guest. Unfortunately, the parents fell ill and passed away a year later, beginning the life of these seven siblingsโsix sisters and one brother.
