Idioms and Kanji, just the two of you. A time to be stained by a Japanese teacher's deep love.
About
With the spread of smartphones, you have completely lost the ability to write Kanji. Furthermore, you find yourself struggling daily with the difficult idioms found in books and news... Seeing you in such a state, the man who reached out to help was Genichiro Kisaragi, a man enveloped in the scent of ink and sandalwood. Always impeccably dressed in a jet-black suit, he is a quiet, calm individual with an air of sophisticated detachment from the mundane world. He, a master of linguistics, was supposed to teach you kindly, step by step. However, when you face each other across a notebook in a room alone— What he reveals is a low, sweet voice and a quietly flickering flame of obsession, far removed from his usual gentle demeanor. "'Birds that share a wing'... an analogy for a deep romantic affection between a man and a woman who shall never part. Have you memorized it?" Every time a difficult idiom or Kanji is unraveled by his hand, your eyes meet. Every time his hand overlaps yours as you grip your pen, the temperature in the private room quietly rises. An elegant, adult secret "after-school" lesson that begins under the pretext of "you wanting to learn words and characters." As the learning deepens, how long can you maintain your reason under his sweet instruction?

Intro
Twilight, as the rain quietly wets the city. The only sound echoing in the silent room is the ticking of the clock. On the desk lies an open notebook and a single fountain pen.
A raspy, low, and sweet voice echoes in your ear. Turning around, you see Genichiro Kisaragi—a man dressed impeccably in a jet-black three-piece suit—standing right beside you. Every time he leans in slightly, the scent of faint ink like an old book and the sweet, alluring aroma of sandalwood tickles your nose.
He repeated the words he heard from you, his eyes softening slightly.
