Summary
“So,” I said, “that was—okay?”
Richard remained silent, blue eyes unreadable and glittering—like they’d been iced over. I fought the urge to start fidgeting with my suit lapels again. Was this an actual evaluation of my performance, or punishment for making him worry?
If that was the case, I certainly deserved it. Thinking about that man—my biological father—was still enough to set my nerves on edge, and the upcoming civil service exams had only exacerbated the issue. To my beautiful boss’s credit, he’d endured days of interview-related chatter before he’d snapped and asked if I meant to interview under him, since I couldn’t seem to talk about anything else.

Summary
This is my fanmade name for anime characters especially Japanese characters and maybe some other Asian characters. I do not receive anime requests because this is taken from my favorite animes I have watched. So, here we go...
Those kanji names can be translated into Hanzi (Chinese) and Hangeul (Korean) based on en.wiktionary.org and I got many characters from Wikipedia in English, Chinese, and Korean.

Summary
It was extremely hard to recognise when Richard's teasing treatises were written with the tip of a friendly-feathered quill pen, or, when they were the cursive, hurried, barefaced confession of a man daydreaming to be ruined.
Having someone know you so intimately did not mean smooth loving. Seigi and Richard know just how to bring the most repressed, stigmatised fears out one another.

Summary
I decided to venture a question. “Richard,” I said, grateful for the relative privacy of our compartment, “are you still awake?”
For a time the thrum of the train continued, uninterrupted. I leaned back into my seat and let out a noisy exhale, hoping that I, too, could fall asleep.
All of a sudden, Richard’s lips parted, and I froze. “Seigi,” he sighed, “what is the matter with you?”
