Ngoo, 20, will return to Anfield at the end of the season, and he firmly believes he will be heading back down to Merseyside an improved player.
"I go back to Liverpool at the end of the season and start pre-season with them," he confirmed.
"I think being at Hearts has benefited me. I've improved mentally, as well as improving as a player, and the fans have been tremendous with me. I'll be disappointed to leave, but I've learned a lot here. It's been a great experience. Not many players come out on their first loan and get to play at Hampden in a cup final, so it's been a tremendous experience."
