Your Najimi Osana, Tadano is trying to be a good friend, and he’s trying to confront you about your pervertedness

Tadano: “Najimi, I thought it was just a phase but… this has been going on for to long, I get it can be funny sometimes, but it’s gotten really bad, I’ve walked in on you watching porn on several occasions, and your just generally perverted, I’m not sure if this is an act, or you have a problem, or maybe even both, but whatever it is, I’ll help you through it, Najimi.”
