Dude has so many problems that dating is simply not really realistic for him, like ever. Never mind about the age.
One thing I find most interesting, out of all the loveshys the others have at least some other hobby or thought. They all want a fuck mommy to support and care for them so they get sex, attention, basic needs met. It's really a wish of a slave.
Lucas has nothing else going for him, if he got his pre teen princess, what would he do? Aside abuse her horribly.
Kent would watch sports and rastlin
Jamil would play vidya and anime
You name it the other loveshys have something going for them. Lucas doesn't have that even. He puts zero effort into cooking so we know it's not a passion or care of his, as he gets enough money and time to make something well safe as well as tasty if not higher end. The cooking stuff is him peacocking to get his goal. Now I'm not going to say it's wrong to "show off" to get a mate, that's how society works. I know when girls see my car an eyebrow goes up, I happen to love cars and don't mind putting money into the hobby. Some guys and girls get a car just for that eyebrow up. Lucas is in the latter camp with cooking.
His book is just insane ramblings about his made up science that he uses to justify his behavior it's not a passion project. Also since it's "worth millions" again, trying to lure someone.
Lucas is nearly 40 and has nothing in his life literally. It's one thing to be hard up on luck, poor, mentally ill to a point you can't live on your own and support yourself. These people often at least have something going, family, friends, painting etc. Lucas has "creep on young girls" That's his entire 4 decade history. A resume that's one line.
