Surely you would have known about this; just a short summary here.
In short, you could say that Manila is his final (solo) activity decided even before the official notice of all final termination with ex agency company was released last week.

SS501 leader Kim Hyun Joong attended to Philipine Manila's charity concert 'Kpop meets Ppop' on the 19th June at Manila's Araneta Collosium alone. Despite facing contract problems, he still took time to stand on the stage of this charity concert in Manila. Kim HyunJoong forked out 1 million pesos at the beginning of this year and donated it to charitable organisation 'Abriertas House of Friendship', this amount of money was used to help the poor high school students with the building of their classrooms and educational environment.
In order to express their gratitude, Abriertas House of Friendship prepared a token of appreciation to Kim HyunJoong, but to this, HyunJoong rejected having to receive it on the concert day itself but instead chose to receive it laterwards in the backstage lounge room on a personal basis.
On the otherhand, after completing his schedule in Manila, Kim HyunJoong will be pausing all his current activities due to problems of his contract issues with current agency company. Validation period after signing on with agency company DSP Media beginning since debut days had ended on the previous 8th of June,
whilst DSP company had also made an official announcement notice on its homepage on 18th June regarding final termination to all activities of SS501's.
