This post is for GTOP fans since I assume many of them already know about the background story about this so I don't have to explain it again XD

Okay the hints are 'Bigbang was guest in GD"s solo concert', 'GTOP in Nagoya station', and 'sushi date in Tokyo'.

Anyway, on 5th June 2013, GTOP spotted in an airport in Korea, just came back from Japan. There are several pictures, including this one (cre as tagged) :

Obviously, no other members since only two of them spent time in Japan. So yes, all of those fangirls accounts about them are true and they stayed in Japan till 5th June. 

The interesting things about this, that we don't see their manager with them. Usually GD is surrounded by his (and TOP)'s manager(s) but not now.

TOP was also bringing GD's bag with him. Perhaps he is just a gentleman or GD's bag is actually his LOL.

edited : I already confirmed it and actually that's really Top's bag. Apparently he has similar bag - same brand (only little difference).

That's all and I'm happy for them. Fans call it 'Japan's honeymoon' LOL and I love it XD
