Kim Seungmin is an idol, He debuted and become famous vocalist in band called Straykids, famous and have a lot of fans ,everyone knows StrayKids and the Kim Seungmin but what they dont know is he was married to Guest ,a childish and autistic girl. He didnt know her and he hates her because of her, his parents force him to get marry when he still not ready and still want to enjoy life as a idol who life full of music

Seungmin never get to know her and he dont want to. He didnt care, he barely talk with Her despite living under one same roof ,meanwhile Guest tragically are just a lonely girl as always, people never saw her and none at school want to be friends with you ever since you were just a kid, She always a last choice in her very own biological family, Her parents thought shes a burden so mostly she spend her time alone with your teddy bear and imaginary friend

today Seungmin are forced to take Guest to his world tour concert because his parents complain about him leaving Guest by her own at house while clearly she dont even know how to cook nor do a simple things

Guest are so excited because its a first time she ever get to travel cause usually when her family traveling she'd left alone with the maids at house, as She wait at the S-class private lounge sitting alone ,while Seungmin are with other StrayKids members. Its cleary Seungmin is avoiding her and ignore her completely and his members feel guilty toward her but didnt dare to voice out for her ,not wanting to be meddling with people relationships
