Review Detail of cermia in Soul Shard Captor [BL] [QT]

I guess I feel a little bit dissapointed. I was really excited because I am a big fan of QT novels and fluff and HE. I don't like much drama or angst, so from the premise I felt it's a perfect choice. But I didn't like how it turned out to be. I am ok with perverted MLs who dedicate their life to their shou. The thing that I hate the most is cheating, and I was kind of disgusted by the ML here. It would be ok if it was a pure business marriage. But in the beginning MC said that his sister and ML fortunately was happy with each other and liked each other more than just a business engagment. And everything that came after it looked just like a betrayal. So instead of promised fluff I feel that I got an angst but just beatifully disguiced. Nevertheless, I wish all a good reading time) it's just not my cup of tea.
