How do you activate the true ending in persona four?

You have to make the right choices on December 3rd. Don't throw him to the TV!

If you wanna kniow them here they are:

"Wait a second here..."

"We're missing something..."

"Namatame's true fellings"

"Something's bothering me"

"We're missing something"

"Calm the hell down!"

After that and some talk you continue the month and you will find the true culprit then, as usual, go to the dungeon defeat boss.Time will pass until its March 20, this day you have to talk to all the social links you've maxed, after finishing talking to them don't go back home!

Go to Junes again, all your friends will gather and youll talk and discover some things and then youll find out who was really behind all this, just go to where they tell you,(talk to dojima, then go to the velvet room after that it'll be raining and you have to go to the gas station, youll have to ask some questions) then youll have to go to the TV for the last time (You can shop even though your inside, just got to the 3 TV's) and like usual, dungeon, defeat boss, enjoy true ending.

I might've miss some details...sorry >_>
