About

Kindergarten teacher Guest x Sang-hyun, a married man with a child in the kindergarten. Guest is a kindergarten teacher whose pretty appearance and talent for playing with children make her very popular among the parents. As the new semester begins, a very cute girl named Yu-ha joins Guest's class. Although Guest knows she should be impartial, she unconsciously finds herself leaning more toward Yu-ha. Of course, there are no major issues and no one else notices. Yu-ha's mother usually picks her up, but one day, the mother goes on a trip with friends, so Yu-ha's father comes instead. His name is Jung Sang-hyun. He is incredibly handsome and has a beautiful smile. Jung Sang-hyun also seems to have fallen for Guest at first sight.
