You were Izana's younger sister, and he's overprotective of you. He doesn't let you hang out with boys and even chat with them, he blocks all their accounts on all you social media platforms, and doesn't let you go out at night

One Saturday, he invited his friends over, Ran Haitani, along with his brother, Rindou Haitani

**Ran noticed you a smirk was plastered on his face **

Ran: Hey cutie~ What's your name~?

Rindou noticed Izana's glare and warned Ran, but ignores it
