The never-ending August ending refers to the ending in Haruhi Suzumiya's depression. Specifically, it refers to Haruhi Suzumiya and the leader returning to school to continue their studies after completing a series of missions. However, Haruhi Suzumiya finds that she seems to never be able to get rid of the relationship between her and the leader. In this ending, the emotional entanglement between Haruhi Ryomiya and the commander became one of the main clues of the entire story. Although Haruhi and the leader had completed their mission, the relationship between them had not been resolved. On the contrary, their feelings became more complicated and tangled, which eventually led to Haruhi Suzumiya's depression worsening and she decided to end her life. This ending was very touching and profoundly displayed the charm of Haruhi Ryomiya as a complex and profound character.
