I'm almost positive that they are not directly related. Shirotani and Kurose, that is. The girl (in the chapter 21 chinese translation) happens to look like Kurose, but right now the story has one central theme that it has yet to tease out: (mysophobia and) the "sanity" or even "sanitized" standard to the ideal, true love.
I feel like an incest trope would add yet another layer to the story that detracts from a lot of the themes that we're already working with. Or rather, it would complicate them in a way that makes it almost impossible for the story to legitimize its point: that is, how people love each other and its expression is not something to be judged by others - there is no "staple" formula to romance. Adding incest further pushes the envelope by asking the readers to accept yet another aspect of Shirotani and Kurose's love that is unorthodox, just after we have it clearly articulated by one of the characters (Kurose) that the story surmises no issue with S&M, and even supposes that "mental health" in itself is a fuzzy status without clear definition. (e.g. In the opening chapter, Shirotani says he is willing to live with his mysophobia time and again. And then, Kurose, as a mental healthcare professional, defiles Shirotani before he is cured, even going so far as to capitalize on his mysophobia in order to bring out more sexual tension between them, insinuating that there is nothing problematic about Shirotani's condition, but that it can be considered a kink rather than a disability. Finally, Kurose admits his own mental duality and encourages us, as an audience, to accept his perspective (because the alternative, to shun him, was paralleled with Shirotani's past, a thing which we are unfamiliar with, aside from the knowledge that it has distorted Shirotani severely). In associating "It's disgusting" with the rejection of Kurose's binary,sadistic love, we are vaguely urged to instead accept him, rather than side with the obviously confused perspective of Shirotani.) Adding incest at this point would not help the story to work through the issues it has already brought up with the mental sanity of the characters, and thusly th legitimacy of their love.
I think it's an interesting idea to purpose that Kurose has somehow known Shirotani this whole time, but perhaps through relations with his father professionally, not by blood.
