FYI, This could probably expand into fanlore. Some of this is derivative from canon, some of it isn't. This is purely for fun!
-Mutsuki & Sumire are T4T. They lend eachother old clothes and generally help eachother transition.
-Sumire confessed to Mutsuki first, and Mutsuki had reciprocated said feelings for a while before she confessed. It was like a "Hey, I like you a lot..." kinda deal.
-Mutsuki's jacket in INNOCENT 3 originally had belonged to Sumire, the apples he bought were for an apple pie baked for him & Sumire's anniversary.
-Mutsuki holds support for Sumire despite her literally trying to disrupt the universes peace. Despite this, he doesn't seem to care as she always fails either way, unfortunately.
-Sumire's uniforms are designed by Mutsuki & Timer, Mutsuki draws them, and Timer makes sure the costumes are a good fit & aren't too tacky.
-Before Mutsuki & Sumire started dating, Mutsuki's sketchbook was filled with little drawings & doodles of Sumire, He hadn't known her name until he mustered up the courage to begin talking to her.
-Sumire's henchmen, Up-Up, frequently go to Mutsuki's place when Sumire is busy. Mutsuki gives them milk & cookies. :)
