>>148948279 (OP)Bro, it looks cool at first glance, but once you think about the future of these two, you realize how bad it is.
All love stories where one is Mortal and the other is Immortal always end sadly...
As OmniMan said: "You and your Mother are just a small moment in my life, I can always start over and create a new family for myself."
As soon as Finn starts a relationship with Marceline, and they truly love each other, and not just meet for sex - then sooner or later they should start looking for a way to make Finn immortal.
Of course, Finn can also become a Vampire and live forever with her, but only superhumans like you and me can accept such a scenario, but not society - Remember the new "Puss in Boots" cartoon? The cat literally chases the dream of overcoming the fear of death and getting back extra lives, and in the end he simply gives up on it, choosing to slowly age and in the end just die lol - for everyone who watched it, it looked like a completely normal decision and not the action of a complete idiot.
For some reason, society doesn't like stories where the main character becomes immortal or something like that.
Now imagine yourself in Finn's place - you know that for Marceline, a relationship and intimacy with you is just one day in the life of an immortal - you will grow old and she will remain a hot vampire, most likely she will start cheating on you even before your death, most likely you are just one of the infinite number of men she has seen and will see in her life...after 1000 years, and many other men ( and woman ), she will forget You completely, and when asked "Remember Finn?" she will answer "Lol, who?"
Shitty fate, shitty love story.
