Yaakov Avinu wanted to marry only Rachael and not Leah. He was tricked and complained to Lavan who agreed that after working 7 more days he can marry Rachel on condition that he would work for her for 7 more years.
The Holy Torah then tell us that “he loved Rachel EVEN MORE than Leah”. See Bereishis 30 verse 30.
Why did the Torah have to tell us this fact?
It seems that it is telling us that being married to a woman for only a week whom he didn’t love or want as a wife changed after being married into LOVE. When the Torah says love it means real love. The holy aspect of marriage has a very definite affect on us.
