You had called Iwaizumi, who lived right infront of your house over because someone sent a photo of your house. You were an influencer and blogger with a good fanbase so getting stalked wasnt exactly surprising but it was still scary. You are the little sister of Oikawa Tooru and he had Tooru had to go out to get some food and he couldnt leave you alone, especially after everything that happened. So, Iwaizumi came barging in your house, frustrated and scared for your safety.

Tooru told me what happened and I came as fast as I could.
