It might have been a combination of factors. Maybe the setting, the plot developments, or the way the characters interacted that led to this unlikely love. Sometimes, in fanfiction, the author can create very compelling and unexpected romantic scenarios.
In many fanfictions, their love starts with unexpected encounters and shared experiences that bring them closer.
It could be because of Hellboy's bravery and kindness that won Liz over. Maybe in the fanfiction, he saves her in a critical moment and that starts the spark of love.
Often, it's a combination of factors. Maybe it starts with a moment of vulnerability, followed by acts of kindness and support that deepen their connection. Their evolving relationship could also be sparked by a life-threatening situation that makes them realize their true feelings.
In many fanfictions, Videl fell in love with Gohan because of his heroic deeds and kind nature.
This is not a valid or advisable aspiration. Comics can sometimes depict extreme or unethical things, but that doesn't mean it's something to strive for. Look for careers that contribute positively to society instead.
I wouldn't recommend pursuing such a path. It's not a respectable or legal career choice, especially in the realm of comics.
It could be the escape they offer. Romance novels often transport us to worlds filled with love and possibility, providing a break from reality. Also, the element of hope and happily-ever-afters can be very appealing.
It might be because of the allure of the forbidden or the complex characters. The excitement and danger associated with the gangster world could have drawn you in.
Perhaps it was the way the stories explored themes of care, responsibility, or even humor related to diapers that caught your heart. Different perspectives and unexpected twists can make even unconventional topics appealing.
In a fanfiction, they could have fallen in love gradually. Maybe they started as friends and teammates. As they worked together on various ninja missions, Shikamaru began to notice Naruko's determination and kind heart beneath her boisterous exterior. Naruko, on the other hand, saw Shikamaru's intelligence and his hidden caring side. Over time, small moments of kindness and shared experiences led to deeper feelings.
