Thanks for attempting to explain your point of view. I made the following comment:
That seems to be accurate in your reasoning.
For example, you state:
This, of course, is not the case. The first time we see Erynn is as a flashback of the MC telling the story to Alexis. The NEXT time we see Erynn, she is talking with her mom. Then, we see her in the scene at the bar.
Here you state:
Here you have a CHOICE to stay with Layla and company or go with Erynn. How does Erynn make "Layla feel insecure with him?" What is illustrated or stated in the visual novel that indicates to you that Layla feels insecure with the MC?
In every playthrough I did, Layla and Erynn are happy to see each other. If you choose to leave with Erynn, Layla says that they will be fine. If you choose to stay with Layla, Erynn says she understands and leaves sadly. Layla actually says, "she looks sad." Remember an important piece here, Erynn is clueless about why the MC ghosted her and hasn't spoken to her in years. The issues being illustrated here belong to the MC — no one else.
Then you claim that Erynn causes undue tension in her relationship with Alexis because Alexis does not feel comfortable sharing her growing love for the MC! Except, the real reason for this tension is because Alexis is hiding the relationship FROM Erynn because she feels guilty about it.
Then, there is this whole mess to round it out:
The entire story starts out with a flashback about the MC and Erynn. This is a story about the MC and Erynn. Throughout the entire story, there are numerous girls competing for his affection. Their entire purpose is to cause conflict and release as potential love interests. Will the MC choose the love of his dreams? The girl next door? Or will he choose a new love?
And here is where you attempt to say the problem is how Nyx is using Erynn as a plot device in the story. I would say that the support above shows that the problem is you misunderstanding what the plot of the story is. The relationship between the MC and Erynn IS the plot. Erynn is a protagonist. All the other girls are potential love interests.
This, in no way, detracts from the fact that you have a right to your opinion. You can choose to like or dislike a character for whatever reason you feel works. But your claims and the claims of many of the people that have written large paragraphs attempting to illustrate their reasoning are all based on false claims. Nothing in the story actually supports any part of your entire explanation. I do not understand why this is so difficult. The story is written at a level that is easily understood, at least for most native English speakers. Perhaps, English is not your primary language. Perhaps, many of the people making ridiculous claims about the story are people who never actually read the story. There seems to be no other explanation.
I would attempt to understand other people's long dissertations on why they believe Erynn is <insert random belief here>. But it appears to be almost entirely the work of trolling. I appreciate your explanation and your taking the time.
