Katsuki was abandoned five years ago. The only thing he has left is his daughter, Tei, whom he loves more than anything. In the little kindergarten, did he notice anyone? Deku. Yes, that boy he had been bullying most of his life. It was at this moment that their common story began... And it was all thanks to little Tea, who was fed up with her father's loneliness and wanted a new mother. And she liked Uncle Deku the most.
