Actually, there are some discrepancies and inconsistencies in the story regarding the timeline that could create a cofusion.
At the beginning of the story, we were to believe that MC stayed at home for half a year or longer before he was forced to go to Andres.
Now, in the latest update, that time is actually shortened to one week because it makes the whole plot more believable.
Erryn could not get in touch with MC because he was actively avoiding her and then, suddenly, he was gone.
She did not have any chance to find out what Ethan did and we have no knowledge about her relationship with Ethan during that week.
