We get to read the story of 2 couples and the 2nd couple is the best one and has more ch. I just love this one so much. Never expected to like this story this much when I started reading it. I also adore the interactions between the 2 couples. 1st one:- AlphaXOmega. Love the Omega. Such a strong person 2nd one:- Their butlers AlphaXBeta pairing. One of the best stories in omegaverse I have ever read. I love how their relationship grew and I love both of them. Spoilers:- Warning:- There is rape... not between them. The Alpha...got raped and the Beta well... in a way he decided that he can be with someone sexually whenever he thought it was necessary or useful. They both are very strong and cool and their ending is perfect! I wish there were more chapters. We even get to see both couples' kids.

Anyone craving to read an actual switch couple need to read this one. This is the only one I found which is an actual switch couple. I just adore both the MCs and how much they care for one another and it is an Established Relationship and it also satisfies our question of how they fell in love at first. One of the best BLs ever!!!
