It all matters on true love. I don't really care who he falls in 사랑 with, as long as he truly loves them and knows it's right. 사랑 is about knowing in your 심장 that the person your with makes 당신 happy and that when your with them everything feels right. If it isn't right from the start then waiting to see is what to do. So he should be with the one who makes him feel this way, it doesn't really matter who we think is best for him, it is only if he feels it is right.
