KAT-TUN Chain LIVE TOUR 2012 - Osaka 2012.03.04
During the game segment, Ueda wanted to name his group "Ikemen (handsome guys) team". Nakamaru said if Ueda is a ikemen, he should be in Nakamaru's group and then said Ueda is not a ikemen. Ueda got angry and kicked Nakamaru on his knee but Nakamaru didn't take the hint and continued to shout that Ueda isn't a ikemen.
After that at the MC, Ueda didn't speak and just went to sit alone at the steps. Nakamaru finally realized he went overboard and went to sit with him. Then Nakamaru started talking to Ueda but it seemed that only Nakamaru was doing the talking. Not long after, Ueda walked back to the stage and Nakamaru immediately followed, and the two of them went backstage to change clothes.
Soon after, they returned on stage, but Ueda remained down even after MC. He didn't smile at the end of his solo, didn't fan service and also didn't jump about in the performance for Peaceful Days. During encore and 2nd encore, Ueda also didn't reply or react to Nakamaru.

On 2012.03.07, when KAT-TUN appeared on NTV's Power of Music 2012 (Ongaku no Chikara), Ueda still seemed down.
However, by 2012.03.08 during the recording of R-One KAT-TUN, Ueda and Nakamaru had reverted back to their friendly status and were joking around in the programme (broadcast on 2012.03.13). On Nakamaru’s Page 2012.03.09, Nakamaru mentioned that they recorded R-One KAT-TUN the day before and he ate strawberry daifuku during the break.
At the Marching J event on 2012.03.11, where Nakamaru was absent, Ueda also mentioned Nakamaru’s name a few times, an initiative which is not very common for Ueda.
Translator's notes: I’m curious as to how Nakamaru managed to appease Ueda. Perhaps the strawberry daifuku helped ;)
