Aw thanks! I do try my best!
Oh hmm... At the very least their LCB selves I don't really see romantically. But they could still hold an interesting dynamic as fellow Sinners. I feel like Outis would at first deride him as someone whimsical and a wimpy rich boy. But after some careful observations of his habits I think she'd become increasingly wary of him and the glimmers of insightfulness he displays. Plus she'd be capable of recognizing his physical strength and martial prowess and know there's more to him than meets the eye. Meanwhile I think Hong Lu has her clocked from the very start, what with his airheadedness clearly being a facade. He's more cunning than he lets on, so I think he'd be we aware of her and keeping an eye in her on the sly. Little Spy Vs Spy kind of action. But as things stand now I wouldn't see them as shippable.
But if we're talking Mirror Worlds, I think the two that they share are W Corp and Kurokumo/Blade Lineage.
W Corp I could see it as a workplace sort of thing if it developed maybe. Since Hong Lu appears to be in a subordinate position to her.
Kurokumo/Blade Lineage is where I see it being the most viable. Much spicier, faction rivalry stuff. Duels that become bloody grudge matches which could lead to clothes being ripped while the blood boils. And then quickly parting again in the night before the sun sets. A serious leader and a frivolous but deadly younger member of opposing factions.
That could be fun, I think!
