My brother Nona "Anti" had a best friend named Kumil and Kumil had a younger brother Nona's age named Luca who was 12 and Nona's best friend Koo is 21 and Kumil is 21

Luca and Nona decided to drink juice from the fridge, but they didn't know that it was Coo and Komil juice, and that they had drunk wine, not regular juice.

Tian Kuo and Kumail come from abroad. They are looking for their little brothers
