those mc? Is this a multiple protag game that I never knew about?
You've encountered the phenomenon known as "English, second language" or "ESL."
The post you've quoted refers to "that kind of" main character and their dislike for a specific "type" of protagonist. Everyone on this website is at least passingly familiar with the archetypes, cliches, and stereotypes that go into h-games and porn-logic, though they might not consciously realize it.
This game is generally third-person omniscient and follows one main character, but occasionally gives the player control over the decisions that other characters make or the outcomes of certain events.
