Ouran High School Host Club (2006) : 1x7

The Host Club drags Haruhi to an artificial tropical beach, but an accident separates Honey from the rest of the gang. Mori and Haruhi separate from the rest of the group to look for him, Mori eventually carrying her due to her slowness and clumsiness. Haruhi wonders aloud about Mori's and Honey's relationship, and then twins explain that they are in fact cousins by marriage. Meanwhile, Kyouya's guards, called in to look for Honey, end up mistaking Haruhi as the "small boy" Kyouya had described, and, under his orders, attempt to arrest any "suspicious people", as they believe that Mori looks suitably suspicious. Honey swings in on a vine, amazing Haruhi with his martial arts ability. The gang returns, ending the episode with Haruhi noting, much to the surprise of the twins and Tamaki, that she would enjoy visiting a real beach.
