My personal opinion, Chapter 5.2 was a good turning point in Lizana's story. Yuki finding out his mom is fucking his grandfather and him getting a blowjob from her. Now, the story could have continued where Ramon teaches his grandson how to please his mother using his mouth and dick, Ramon and Yuki double teaming Lizana. Yuki taking Lizana's anal cherry since she would take his. Etc .... So much potential lost.....
