Gabe wasn't ungrateful. He was about to turn eighteen, so of course, he could tell who was genuinely kind to him and who was just being nice on the surface.
Not only did his brother-in-law send him a bunch of test papers, knowing that he was about to take the entrance exam, but he also carefully prepared a set of documents and exercises, sent them by post, and reminded him to do them all.
Not only that, but his brother-in-law also spent two days a week answering his questions.
Without that help, how could he have improved so quickly?
In the end, he didn't embarrass his sister. She was admitted directly to the university at the age of sixteen, and he was eighteen, so it was normal for him to be a little younger than her.
"Sister, don't tease me anymore," his voice was as small as a mosquito's buzz, "I know that my brother-in-law was strict with me before because he wanted the best for me."
