It seemed a little tense in the beginning but when Nakamaru and Taguchi showed up, it was pretty lighthearted and it looked like Jin felt a lot better having his fellow members with him and Jin kept joking around with questions.
They mentioned Kamenashi, and his little note to Jin and Jin laughed, and apparently they had a heavy and deep conversation on the phone the night before that was sort of like a goodbye. They also mentioned Koki, and his note to jin saying that he wanted Jin to work hard and he (koki) himself would work hard until Jin returned and Jin said that by that time, Koki's hair would've probably grown in (or something like that...)
Then they tried to say K?t-tun without the A and it sounded funny and everyone laughed. Then Taguchi and Nakamaru said that they didn't need to pronounce it differently because they weren't changing the name...Because Jin is still part of the group and Jin smiled a really happy smile at that which made me happy. And he sticks his tounge out. Twice, I think. wtfomgbbq. It seems pretty light hearted, though this *is* JE we're talking about and they're a bunch of cold hearted bastards who treat their idols like crap (Not paying them enough/ messing with their lives) but things look a little better than before and I'm willing to hope that Jin might come back as he said he has no intention of leaving Kat-tun at all.
That's about it. Sorry for the loose translation everyone!
Edit: Though it's hard to say so, I really hope this won't affect the fandom too much because they're still a group and they're still Kat-tun, no whatever what. Jin says he's only leaving for a little while and I hope everyone supports him even if he doesn't! He's got five very good friends backing him up and I think as fans, we should do just the same! I'm glad everyone's sharing their emotions with one another, and though I may sound sappy and lame, I hope that we can cry or smile or laugh together as a fandom! I love you guys ♥
