The series is quite good, with great characterization, interesting world politics and very nice art. As always these transmigration stories end up all about god, fate and the predenstined but I was half expecting that. The last 20 chapters are more of an epilogue, with the story proper ending at chapter 120 more or less; this is where the series, for me, dropped from an 8 to a 7. The art is still good, but the major conflict has been resolved and we got our happy ending and, unlike other series like this one, "Marriage of Convenience" doesn't have a cuple of chapters for epilogue, but 20,which is in my opinion too much for the uninteresting story they told.
Still, I do recommend it
