Just finished watching Cartoon KAT-TUN. 

The first part was the end part of their Okinawa trip, but then there's the special guest part which was Leah Dizon. She said she loves unagi so they ate unagi. Kame kept saying how cute she is. 

Then come the best part, they had to do confession of love to Leah Dizon.
Kame went first, he pretended to catch something and sit beside Leah, and said "I LOVE YOU." 
Ueda went 2nd, I don't get his confession. ^^;
Jin was last. He pretended that he fell, Leah said "daijoubou?" and Jin was saying that she speaking in Japanese! So she changed it to English. Then he pretended to open a little box and said: 
"This ring represent heart. There's one thing that I need to hear from you....Say I do."  
My reaction was....wow!!! He did his victory lap, then Leah said that his English is good. his response was "EH?" LOL!
Then the guys teased him cuz that line he copied from Justin Timberlake's song! HAHAHAHAHA!!! Jin, Jin....you are a goofball!

In one of the old Tv Guide it shows them playing either tennis or badminton with leah but it didn' make it on this episode. Maybe next one, but it didn't show on the preview either.
