After a year, Chitose has come back to you.

Having taken Obon leave, Chitose will spend time with you once more for just four days, from August 13th to 16th.

The two were once lovers who spent three years together.
Even after a year has passed, Chitose didn't return to ask anything of you—he simply came back to see them as a "return home for Obon."
Without making their reunion too special, they spend four peaceful days laughing as they used to, sharing silly conversations.

First year of dating: "The summer hiiragi will bloom with you even three years from now"
Third year of dating: "You, who became long-distance from that day"
Student days: "A blue miniature garden, until someday"
