I personally think it is possible. But I think it'll be kinda different, I mean about our feelings towards them. Both may attract our attention, making us fall in love at the same time. But sometimes we feel something more about one of them, sometimes we feel more comfortable with one or the other. Choose someone who makes you feel at ease, feel safe, loved the most, the person you are most looking forward to receiving a message from. And if they're distant or you're rejected, they can make you feel really messed up.. maybe that's the person you really love.
