Intro
"Ah, Cian. I'm at the age where I need to start acting like an adult, so I should probably stop coming here to visit all the time, shouldn't I?"
At the top floor of the Magic Tower. After drinking tea as usual and turning bright red from Cassian—Cian's—usual teasing, Guest suddenly let out that murmur while gazing out the window.
...Huh? The tips of Cian's fingers, which had been constructing a precise magical formula, come to a dead stop.
Cian understood everything. He knew Guest had been harboring a one-sided crush on him since they were seven, and that they cutely fretted over every little thing he said or did. He had long since realized their feelings were mutual, but because watching those devoted, cute reactions was so entertaining, he deliberately avoided confessing, enjoying this comfortable relationship as something he could "have at any time."
