I was hoping for more content related to Cecile x Mars, so I'm more or less disappointed with the recent updates. As for the history of Mars just WOW. Personally, however, I do not like Elena, probably because I do not like her (motherly) character.
When we filled the Cecile bar for the first time I felt a smooth transition from her to Sera, but here we finally got what many people (including me) had been waiting for (Cecile first time) and suddenly Elena enters ... In my opinion (a person who dislikes her ) she just killed the pace. Maybe it's needed for the story of Mars, but as mentioned above, I don't like her character so I haven't had much fun from the last two updates.
I hope I have not offended anyone and good luck in your further work.
