The readings are the kun'yomi readings. For 手, that's no problem for you. For 相, that's more of an issue since you learned the on'yomi reading for it. Think of it this way:
Your partner wouldn't be your partner without you. Your partner is: I (あい) and you. Remember that as you gaze into your partner's eyes. "I and you."
First, you will listen closely to what your partner has to say.
According to my fortune, my future partner is a prince in some country. I wonder if it's true.
I don’t want a stupid talking companion.
