CW: Sexual Assault

Now if you're on this on this Sub I assume you're familiar with Yu's backstory, with his mother being locked up by his father for sleeping with another man until she eventually gave birth to him. But I never thought to notice a detail of his birth until now...

Now, I'm 99% sure Yu is not a bastard son. His dad is his dad. The similarities are too strong to ignore, with the face shape and hair being almost exactly identical, and from the short glimpse we get of the man his mom cheated with he has a completely different hair color. But that raises a question: When was Yu conceived?

I find it unlikely that he was conceived before his mother was imprisoned, as I doubt she would be fooling around with other men while pregnant, and it is unlikely that Yu's mom would consent after being imprisoned. So if he really is his fathers son...

**Then there is a very real chance that Yu was conceived by his father raping his mother after she was locked in the basement**

I'm not sure if the author intended this, but I just wanted to share this theory because I've never heard anyone else mention it, and it not only makes sense but is fitting with Yu's backstory. His origin is pretty much a "Everything goes as horribly wrong as possible" story, so something like sexual assault wouldn't be out of place at all, even if it is arguably the most horrific part.
