i think in real life......as long as u feel someone as your family/relative ,even if u r not related by blood....and u have relationship with them it is incest
as far as i see in manga it justifies ,....if u r not blood related its not incest
just keep an open mind......do not judge....all of us when we are born we have no rules whom we can love or not.....everything we follow is simply rules of society,to be socially accepted and not be an outcast
scientifically speaking when 2 ppl have sex and have a baby (not talking about gay relationships)......all it counts if u r a male or female.......only the process and outcome counts......evenif it is an incest relationship baby will be born....so nothing is wrong or right.....its all ur mindset.......keep an open mind to explore infinite possibilities.....ur morals should be what u want and not what society expects of u....so i never judge
Ahh the age old step-siblings/ cousin quandary. This is one actually does happen in real life and is another morally gray area. I too personally think of it as incest when you purposely are raised in an environment that see's one another as immediate family, but it's another one of those well they're not really related....(at far as step-siblings go)
What are people's thoughts on stories where one character adopts and raises the other like their own child for years, but then they start a romantic/sexual relationship later on in life even though they're not physically related? Do you count that as incest why or why not? I always feel iffy on plots like that and honestly find the thought of it uncomfortable, but wondered how others rationalize it.
