– He pretends to be previously wounded by their sass, but he absolutely loves it. And he’s pretty terrible at concealing his admiration for their barbs.
– If their sass is directed towards someone else, Tsukiyama hang in the background, using hand motions and even interpretive dance to “accentuate” their words.
– He designs an outfit specifically for them. A sassy outfit. Probably lemon-colored for sourness.
– Watching movies and TV together is one of his favorite activities. His S/O’s commentary is gold.
– Their, uh, lovemaking times are always fun, too. If Shuu feels insecure (which is admittedly rare, but happens because he’s a person), his S/O’s snark is just what he needs to cheer him up.
– One day, he wakes up besides them as dawn arises and declares most seriously that they are a breath of fresh air (as a breeze sweeps in the open window, because it’s Shuu and he loves drama). And that he wants to spend the rest of his life with them.
– In that moment, they say nothing for a moment before blurting out, to his delight, “Took you long enough.”
