I don't have enough context to determine exactly who 'garp' is. It could be a newly created character by the fanfic writer, or it might be a character from a relatively unknown story that is being incorporated into the 'ace fanfic'.
I can recommend the following novels that are similar to The Dragon's Fast Son-in-Law:
1. 'Dressed as an unlucky concubine's daughter, targeted by a powerful minister's brother.'
2. 'The male protagonist always wants to suck my spiritual energy.'
3. "A General's Wife."
4. " The adopted daughter of a wealthy family is reborn..."
These novels might have similar plots or topics to The Dragon's Fast Son-in-Law, but the specific content might be different.

However, eighteen years later, these people, who had started their business because of his dragon blood, went back on their word. They looked down on him and canceled the engagement. Dragon Eighteen was determined to take revenge and kill the Dragon King. The novel was captivating with its thrilling plot and fascinating world. Unfortunately, I am unable to provide you with the full text of 'As a Dragon Son, Your Father Seized Your Life at the Beginning'
