What I was trying, why he would go to Cube, if he has the J Tune, or maybe in the process i missed information. He isn't the owner of JTune?!
From Wikipedia (the numbers are references to different sources):
In July 2010, Rain reportedly sold his shares of J. Tune Entertainment to his mentor Park Jin-Young. In December 2010, Park Jin-Young announced that J. Tune Entertainment would be merged with JYP Entertainment. JYP Entertainment become the largest shareholder in J. Tune Entertainment and it is viewed as a strategic alliance between the two companies.
J. Tune Entertainment and JYP Entertainment's fusion
With all those "JYP and JYPEnt are not the same", subsidiaries and stuff, that thing with companies is a mess, to be honest. Leaving companies aside, I care much less about business and enterprises and, as MBLAQ's "father", I care about he is still with them in spite of both sides being in different companies. I am not fond of the perception of Rain as a "traitor" while MBLAQ and Rain keep their mouths shut about the issue at the moment. Once they have exposed their point of view, I will try to understand even the negative opinions.
On a side note, it's already 25th of June in South Korea, what does it mean for us...
AHA! THE MAN OF SEOUL IS NOW 31 YEARS OLD!
