Sorry but I already pair Leifang and Hitomi as my otp.
They're more likely to end up with Jann and Hayate respectively than with each other (especially considering Lei's story mode in 5 was all about her stalking Jann). Meanwhile, Tina was already flirting with Mila on their first meeting (she said Mila was too pretty to be an MMA fighter) and Mila did spend most of her time in 5's story mode hanging out with her so...
That's how my parents met, fighting over cabbageLeifang and Hitomi did fight over a cabbage though so I think its safe to assume their in love.
Oh my Tina, getting that action huh?
