Often, a cliche childhood friend onee-san manga has repetitive tropes like the childhood promise that always comes true or the overused protective older sister stereotype. Also, the story might lack depth in character motivations and have very straightforward story arcs.
Well, in many fanfictions, their relationship often develops through shared experiences. For example, they might go through tough times together, like dealing with threats to their family or the Earth. These experiences bring them closer and make their kisses more meaningful, as they represent a deeper bond formed through adversity.
Often, such stories have predictable plotlines like the childhood friend protecting the protagonist or having a secret crush. The characters might follow stereotypes too.
It could be that Gohan and Goten did something that seriously disappointed Chichi. For example, they might have broken an important family heirloom while playing their rough Saiyan games. This would definitely make Chichi angry enough to kick them out as a form of punishment.
No. Fanfics involving sexual content are not appropriate as they violate the ethical and moral standards. Goku and Chichi are characters from a well - known franchise, and creating such inappropriate fan - made content is disrespectful to the original work and its audience.
One common theme could be the anticipation and excitement around the new life. It might explore how the characters around chichi react to the news of her pregnancy.
Chichi was in the middle of a battle. A powerful enemy's attack grazed her side, causing a deep cut. Blood seeped through her clothes. Chichi, though in pain, fought on bravely. But as the battle ended, she collapsed. Her friends rushed to her side and took her to the healer. The healer worked hard to stitch up the wound and give her potions to ease the pain. Chichi slowly recovered over time, with the support of her friends.
Miscommunication can also be a reason. If Chichi misunderstands Goku's intentions, like when he brings home a strange new power - up item that she thinks is dangerous for the family, and she scolds him without really listening to his explanation. Goku, who is not used to having to explain himself in detail, might snap in frustration.
Chichi fell in love with Goku first. She was attracted to his strength and his kind heart. Goku, over time, grew to love Chichi as he realized how important she was to him.
