It's a Yasaka chapter.
Skip and Loafer chapter 44
>The slutty character has a broken iPhone screen.
I'm glad to see that the mangaka did their research, these little character details make them more believable.
I don't even think she's slutty. She's probably as pure a virgin as Mika. She's just starved for attention and guys are the only ones who give it to her.
So she does understand him.
