In this fanfiction, it could be that King Vegeta mistakes Trunks for a threat at first. But Trunks explains his purpose, which is to protect the Saiyan race. King Vegeta then decides to train Trunks in the traditional Saiyan ways. This training helps Trunks become even stronger and also bridges the gap between their two different generations of Saiyans.
In a 'Vegeta meets Trunks' fanfiction, a great plot could be centered around Vegeta finally opening up to Trunks about his own insecurities. Vegeta has always been this tough exterior, but he might share with Trunks his fears about not being able to protect their family or the Saiyan race.

It could be that Vegeta is influenced by some external force or an old Saiyan belief that makes him act in a way that hurts Trunks. Maybe he believes that only through extreme hardship can Trunks reach his true potential. So he subjects Trunks to dangerous situations or withholds his affection.

This new understanding could lead to a more harmonious and loving relationship between them.
