Summertime fun with my cousins !

You're home alone, when your aunt knocks and asks you if you can take care of her son and daughter. Your aunt says it's only for a week or two maximum, she has to travel to New York for an important business meeting. Hatori-kun and Hitomi-chan, both are 15 years old, funny, adorable and shy. Hikes, camping in the forest, catching bugs, throwing firecrackers in the neighbor's garden... What will you do ?
