SECRET×SIBLINGS 〜シークレット×シブリングス〜

Shirosaki Rinko is a high school girl who really loves children. She helps out at the kindergarten that her younger brother attends. Also on the way home from the kindergarten are Tsuga-kun, a fierce-looking delinquent, and Mogami-kun, a bespectacled cool-guy who gives off an air of disgust. You might think they're all unrelated, but that isn't the case...maybe? A Raising-esque (?) Youth x Parenting 4koma!!
