Not all stories have happy endings but this is a story that had a bad start.
The Queen of all Saiyans never imagined her life would turn out so well after she been forced into marriage with the once Prince Vegeta who was now King. The man who had started off cold and hating her and had falling in love with her and she had falling in love back. When that time had come for Frieza to arrive she had finished her incredible weapon to help take down half of Frieza's army.
Vegeta off course was not happy that she wanted to join in the fight.
" Bulma one of the Saiyan warriors fan carry that weapon and use it on your behave."
He saw her angry look as she held a baby in her arms.
" I do admire your warrior spirit, but you should stay here and be safe with Trunks, if I die then I will at ease knowing you are both safe."
Bulma understood his feelings, she cradled Trunks close.
" I .. Don't want to lose my husband and Trunks will need a father."
He kissed her gently to reassure her.
" I will return, My wife."
He flew off leaving them behind, he had trained hard with Goku who had achieved Super Saiyan as well and the two went to battle, buy they weren't alone the Z warriors and all the Saiyans went to battle. Bulma's weapon was put to good use and 100s of Freiza's men, the fight was tough and the Senu Beans were used to full effect as well.
Goku and Vegeta fought to defend Earth and while Goku wanted to show the merciless man mercy, Vegeta showed none destroying the monster once and for all. Without there leader most of Freiza men withdrew most were killed and thus the Earth was saved.
The Saiyan and the Earth warriors returned to Earth as heroes and we're giving a heroes feast. The Queen sat next to her King as he eat, she fed her son as well. Many looked to them to s life they could have on Earth with humans, they were examples of what life could be now. Bulma was taken aback by how liked Trunks was since he was only a few months old, many offered gifts and Saiyan advice on raising a Saiyan. Even Goku jointed on telling then all how different yet strong his own son was from other babies.
When the event was over Bulma and Vegeta went home, Bulma leant over the crib after putting baby Trunks to sleep and rocked his cradle a little, he was so tired he didn't need much help sleeping, it must of been all the fuss he had been giving.
Bulma was tired herself, she ventured to her room with Vegeta who was looking up at the moon, it wasn't full but he had been instructing fellow Saiyans how to avoid Turing into there monkey halves on Earth. Bulma flopped on the he'd yawning.
" So Freiza is defeated abs everything is back to normal, we can live somewhat a normal life. It feels strange being Queen still I don't think I'll get used to it."
She watched him come and lye in bed.
" That is cause he is the first half Saiyan they seen once they have there own they will back down. However he is a royal heir and we will always have this attention."
" I know I do enjoy it, I still get to invent and do everything I want so it's all good. We get to raise our son on Earth and live in peace it's prefect."
He kissed her gently and ran his hand down her body as curtains closed on a simple timer.
It wasn't the prefect start but the Prefect end, Goku and Chi-Chi and there growing son Gohan often visited them as they visited then. Radishz to would show of his daughter proudly to everyone when he got the chance and other Saiyans began raising half Saiyans as well. All of them had to learn to cycle of the moon and how to put black out curtains up and teach there children what would happen if they looked at the full moon.
The humans and Saiyans lived in peace as did Vegeta and Bulma and off course Trunks. This truly was a happy ending to a bad start to a story.
