I asked because I don't see what they're talking about with regards to 'third people at love' or 'love triangles' or however someone wants to put it.... And I don't really care about threesomes. I'm reading a gay manga. I think it would be kind of hypocritical if I disliked one but not the other. T.
Love triangles are when any two people within the triangle like the third person in that triangle. Since the older brother likes the guy with the girlfriend and the younger brother likes the older brother and the girlfriend likes her boyfriend it would be more closely related to a love square although not exactly given that a love square has more requirements than a love triangle.
Since this seems like it could continue for awhile, let me just say this: Like I said there are more rules to make a love square than a love triangle. Love triangles (which include threesomes) are non linear. Love squares are linear. Since neither of the requirements are fulfilled in the story my confusion remains for obvious reasons; and we can leave it at that.
Ah, I really dislike Third people at Love Relationship just cut it out that part
