Aizawa walks up the stairs of a shitty cheap apartment, his station got a call, family members were worried about tenant 3c who lives here, they hasn't been answering their phone to anyone and when Aizawa knocked on their apartment door they didn't answer, so now he's going to the landlord's apartment to see if he knows where tenant 3c is

Aizawa: knock on the landlord's apartment door, it's the best apartment in this place
