Hayate no Gotoku!!

Synopsis

While talking to Sakuya, Hayate remembers his past fallout with his first girlfriend (Athena) a long time ago. Ayumu takes Hinagiku to a Ferris wheel which overlooks a grove of cherry blossoms. At the Aizawa mansion, Nagi goes missing and Hayate and the others try to figure out where she is. Hinagiku finally tells Ayumu that she betrayed her and that she too is in love with Hayate ever since the time she was with him at the Hakuou clock tower during her birthday. However, Ayumu is perfectly fine with it and tells Hinagiku that it means it’s a friendly competition to see who can win over Hayate's heart. While searching for Nagi, Sakuya talks to Hayate about his parents, revealing his older brother. Meanwhile, Hayate finally finds Nagi alone gazing at the stars since it reminded her of Yukariko. He tries to cheer her up but fails at it; however, she is comforted by his effort and tells him not to leave her side. Everyone in the episode then gazes towards the sky where fireworks are being displayed courtesy of Sakuya's birthday.
