<p>I've thought about that too. The possible between the protagonists are:
-Sam, Cat, Dice
</p><p>-Sam, Cat, Nona
</p><p>-Sam, Cat, Goomer
</p><p>-Cat, Dice, Goomer
</p><p>-Cat, Dice, Nona
</p><p>-Sam, Dice, Goomer
</p><p>-Sam, Dice Nona
</p><p>Nona and Goomer didn't interacted enough to be part of tri-pairings.
