I like toxic yaoi as much as the next person, but hmm I need to let them simmer for now, I don't really get into a ship until there's some substantial material/symbolism behind it all that often, so I'd like to wait for more potential interactions they might have first. I am certainly intrigued by their potential dynamic!
For now - I'd saaaaay I'm on board, but as a sexual tension -> messy one-night stand kind of thing with Ratiorine potentially coming into picture as an end-game (because of course)
