I have no clear idea about 'juego a ciegas manhwa tmo'. It could potentially be a code or a term related to a niche subculture. Maybe you can provide more information to help figure it out.
Ero h manga often contains adult content and more explicit themes compared to regular manga which might focus on a wider range of subjects without such explicit elements.
Hard to say. You'd have to look closely at the story and the interactions between the characters to determine if that's the case. Maybe there are clues or indications throughout the manga that would clarify it.
