59. Kasanoda brings the Host Club an old treasure map, without Tamaki, the rest of the club decides to look for the treasure—and when Tamaki appears, Haruhi blushes. They finally find the treasure but it is an empty box. Meanwhile, Hikaru, Kaoru, and Haruhi accidentally find an unknown hot spring. As Tamaki and Hikaru are putting away the shovels, Hikaru accidentally tells Tamaki he loves Haruhi.
60. Haruhi, Kaoru, and Hikaru go on a class ski trip, during which Hikaru regrets what he said to Tamaki. Hikaru ends up sharing a room with Haruhi. Meanwhile, back home, Tamaki has a dream of his past. Kyouya, Mori, and Hunny worry about him and go without him to the ski lodge. Kyouya, Takashi, Mitsukuni, and Kaoru conclude that Tamaki may never act on his true feelings for Haruhi, a conversation that Hikaru overhears.

He tells Tamaki that they must never give up. At the party, Haruhi tells Mei she has been dealing rudely with love problems. Haruhi goes to the terrace, where Hikaru is waiting. Haruhi rejects him, although he's still one of her best friends. Hikaru asks Haruhi if she loves Tamaki. Shocked by the question, she blushes deeply and denies it, saying that she respects him even if he is bothersome. Hikaru does not seem to buy that, but believes he still has a chance. Hikaru then tells Tamaki about his rejection and that he will not give Haruhi up. He tells Tamaki to face his own feelings.

Haruhi asks for her ootoro ring, stating she likes it because it was a gift, showing how both she and Tamaki are both realising their feelings.
