How does this world work? Was it always a dating sim? Are did they get transported into a dating sim world? Why do all of the characters know that they're in a dating sim? Do people not feel weird about being side characters? Do the heroines not feel weird about literally require by the world to love a boy who doesn't care about them romantically?
The heroines, in the very first chapters, talk about how frustrating it's to be a heroine in a dating sim.
The gyaru dislikes the fact that the game forces her to love Hareta, not because she doesn't love him, but because this makes their love less genuine.
The yandere hates the fact that Misaki can stand at Hareta side at all times, while she can only be with him when events start
The tsundere dislikes the fact that Hareta doesn't love her in the same way she loves him and that she has to compete for affection.
Many other characters have also shown frustrating and sadness over their situation, like the rival character who wants to be a best friend character.
I also want this manga to talk more about the rules of their world
