I'm not for RNG, but if most people want it (which it doesn't seem like) then I wouldn't be against it. The main points I'd be looking for in the case of my characters is a partner with a clear goal to aim towards for Sean and a partner willing to be proactive about strengthening their relationship for Kagura.

Edit: Or to be meta, Sean would ideally be paired up with someone who wants to take the lead, while Kagura would be ideally paired up with someone who wants to do more RPing and character development.
