Why is Naruto acting cold towards Hinata?

There are a few friends who don't understand why naruto shows no interest to Hinata, many people even think Naruto's actions are unreasonable and illogical~~

And I think many people think the same, but maybe you guy forgot the details on these two first pages~~

The three of them chatted happily at first, but after the Raikage mentioned the event on the moon, the atmosphere changed~~

The event that happened on the moon is the key, maybe you can guess some part, I will explain all soon~~
