I liked it. The ML wasn't a complete prick, in fact, wasn't a prick at all. His deception was pretty mild, and wasn't designed to hurt anyone. This story has made it's way onto the list of top ten of this genre on Mangago for me.
This is actually a pretty good story. Two people with painful backgrounds is a norm in this genre, and self-serving deception as a reason for starting the relationship is too, but they are handled differently here. It felt gentle and loving. What I found regretful was the author felt the need to include some gratuitus BBV (Bed Before Vows) action that really wasn't needed. It would have been a good, if not better, story without it, and RL statistics show that their marriage would likely be better too (statistically the marriages of those who wait are longer and more satisfying).
