Getting back to cricket and hitting a hundred gives Kevin Pietersen a lot of satisfaction after the recent controversy but losing captaincy to Andrew Strauss still haunts him.
"Unfortunately that (captaincy) was taken away from me. It's one of my frustrations that what I wanted, he (his replacement Andrew Strauss) has got," Pietersen said.
Pietersen hammered a modest St Kitts and Nevis to score 103 runs from 91 balls, with 13 fours and three sixes and then got himself stumped.
"I got told to (get out). (Andrew) Strauss is the boss and I have no dramas with that."
He provided a sneak peak into the anger that still burns within him following his much-publicised spat with former coach Peter Moores.
"Getting back to playing cricket was something I wanted to do," he said.
"I just wanted to get back playing cricket, to get back in the dressing room with the lads. To get a hundred after everything that's happened was pretty satisfying. It's been frustrating because I did everything by the book, everything I was supposed to do."
The former England captain also expressed disappointment at the way the media handled the issue and was hurt for being removed from the captain's chair.
"What you guys (the media) did to me for a couple of weeks really hurt me. Time's a great healer but I'd like a few questions to be answered first for everything to be gone. I loved doing the job. I absolutely loved it. And I thought we were going in the right direction, the direction that I wanted to take the team, in a positive way," Pietersen said.
The South Africa-born player also said that he is slowly getting back to terms with what happened in recent weeks and playing will help heal the process.
"I knew it was never going to be a problem stepping back into the ranks. I've got back to doing what I love. I love to entertain, I love to enjoy myself on a cricket field and I love scoring runs for England. It's been tough but I'm OK now. Time is healing," he was quoted as saying in The Guardian.
During his innings yesterday, Pietersen also took time out to make the field placements for St Kitts and Nevis leg-spinner Akito Willett.
"I talked to the leg-spinner about his field. It's harsh when you're trying your hardest and you don't have the fields you should have. It's a practice game, a friendly.
"For me, to give someone advice makes me work harder, instead of having easy shots. I try to make it harder for myself."
