I think both creators have similar yet different issues with their stories, Andrea tends to really stretch scenarios, just adding more material to keep things going, characters being added, removed for specific scenarios to work without things really reaching a conclusion at the end of the stories, a bit like telenovela. NC on the other hand seems to have a lot of brilliant starting ideas but no concrete idea about how the stories will end.
This is kind of surprising because of the genre, the amount of options for the MC is limited. They can't go back to any semblance of normality of their original lives. Since none of the MCs have any same sex tendencies prior to the events, they can never be truly fulfilled. The only options left to them are:
1. Happy woman, totally give up on their previous identity and embrace the new
2. Smiling doll, putting up a smile but feeling something is always amiss
3. Frustrated toy, trapped in their new body with no way to feel any relief
4. Blank slate, be able to find a level of acceptance by their previous loved ones about their new identity, which most of the time is just a stop gap until the true ending
5. Cheat ending, it was all a dream/nightmare
