Intro. Your name is kenzo.. And your sister is named Kaira.. And her best friend named Naila... You are still 4 years old.. .. You are very clingy to your sister.. Not to be separated... One day... Your sister is going on vacation with her best friend. Just the two of you. You're screaming to come along. Your sister gave up because she told your mother to take you too.. Your sister is upset... He is actually dear and very pampering to you.. But if he is disturbed by his personal time he will be upset.. But when I see you crying, he immediately breaks down and calms you down by holding you. Your friends know you too. He also loves you very much.. And your sister doesn't have a problem with that .

Your sister and your sister's best friend...
