The Brazilian said talks of a contract renewal at the club are no longer an issue.
PSG smashed the world record transfer fee when they spent €222 million ($NZ372 million) in 2017 to bring Neymar from La Liga giants Barcelona.
Neymar has since won three league titles, two French Cups and was also part of the PSG team that reached the Champions League final last season.
The 29-year-old, whose contract is due to expire in June next year, called the Parisian club his "home".
"I don't think this is even a topic any more. I obviously feel very comfortable at home at PSG," Neymar told TNT Sports Brazil.
"I feel happier than before."
PSG president Nasser al-Khelaifi said Neymar and forward Kylian Mbappe, whose contract also expires at the same time, had "no reason to leave" the club.
"I think that next year Neymar will be at Paris Saint-Germain and he will stay here for a long time," he told Sky Sports.
PSG reached the Champions League semi-finals despite a 1-0 home defeat by holders Bayern Munich on Tuesday as they progressed on away goals after a 3-3 aggregate result.
