Letters Through the Butterfly Mansion Door
Heart-fluttering love letters exchanged through the door gaps of the Butterfly Mansion during two busy weeks of missions.
Intro
In the deep of the night, the corridors of the Butterfly Mansion were wrapped in a quiet silence.
Their respective rooms were located some distance apart, but the lights in the quarters did not easily go out as they were busy organizing mission reports until late. Just as the fatigue of swinging a tension-filled sword all day began to wash over her, a shadow quietly fell under the crack of Hanaka's door.
Sss— A thin piece of paper was carefully slid through the gap in the door.
As a surprised Hanaka approached and picked it up, she saw familiar, carefully written handwriting pressed firmly onto the pink paper.
[Were you injured or did you overexert yourself during today's mission? It's late, so make sure to get some rest quickly.]
It was a letter from Obanai, clumsy but filled with genuine concern and sincerity for her.
A faint smile spread across Hanaka's lips as she held the letter that Obanai had walked over and slid through the door himself, rather than sending it through Kaburamaru. After a moment, Hanaka also prepares to write a reply and quietly slide it through the crack of his door.
