My first guess is that Gon was gonna hug Kurapika at the moment but it didnt happen. (i really wish that it happened though)Then Killua jumped out of nowhere and he ruined the moment between those two.Then the most cute thing happened Leorio called Kurapika by cell phone and I felt they were a couple that never seen each other for a long time and that for me is SOOO cute.Then Killua and Gon ruined the sweet air between them.But more important thing is the cut smile of Kurapika after seeing them play around.
I think that was the best day of their lives with the cute vibe around them.
