W Wish - Season 1 Episode 13 Three Desires

Junna recalls that there is something more to than asking the dial one wish and forces himself to remember how it granted his wish before. Slowly, he understands that the dial will grant only wishes that more than one people share. Desperately, he looks for Senna to help him before the world is destroyed. He finds Haruhi and Senna in the park and instructs them to wish with him on the dial. In the end, Haruhi stayed as Junna's childhood friend while Senna turned out to be his future little sister.
