It's better than I imagined.
Good above expectation. (literally.)
Tomoko is enjoying a CD in which yandere characters speak verbally abusive phrases into her ear. In the featured scene, the yandere boy narrates the girl (the self-inserted listener, Tomoko) is crying. We can safely assume he made her cry somehow.
He says it's her fault he made her cry—she's the "bad" one, not him—because he saw her talking to other guys.
This is a typical pattern in abusive relationships where the guy tries to monopolize the girl. It's so typical there's even a name for it in anime: dokusen-gata yandere 独占型ヤンデレ, "monopoly-type yandere."
And yes, such CDs actually exist. People pay money for this. Here, I googled it and got an example video free on Youtube that has an English translation (you might want to listen it with headphones on so people don't ask what in the world you're listening to. I mean it. You really, really, REALLY don't want to have to explain the lines.):
