Summary
Call me in exactly 5 minutes
There was no other punctuation, no explanation- no anything.
A little cold sweat gathered at Richard’s collar as he was unable to gauge the urgency of the message. Many thoughts– none good– passed through his mind as he tried not to panic.
Richard gets a text and panics a little.

Summary
But ultimately, watching them left a bad taste in his mouth and an emptiness in his chest. There was a word for what he was feeling, the sadness that came from seeing the overwhelming joy of others. He didn’t want to admit it to himself though.
Seigi experiences envy.

Summary
Under the warm light of the floating lanterns, the man turned around. The golden glow caught in his hair, not just blond, but the precise shade of honey that drizzled through sunlight. His eyes, the impossible blue of alpine lakes in midsummer, met mine with startling directness. I prayed he hadn’t caught the little “whoa” I’d let out under my breath.

Summary
“I don’t-”
“You flew across the world to see him. You crossed oceans to find him. Seigi, you looked like you weren’t eating or sleeping when he was missing for that month. You looked like a dead man walking!” She leaned closer and narrowed her eyes at him as she lowered her voice, “By your own admission, you almost shattered a priceless ‘diamond’ in order to free him. Do not tell me you don’t love him.”
Or, Richard and Seigi go on their first date.

Summary
Seigi scowled a little at the remark Richard made. He had made himself comfortable on the toilet lid so he could provide assistance if needed. He leaned forward, elbows on his knees so his eyes could meet Richard’s tired albeit beautiful blue ones.
“So… what happened?”
Richard sighs and relaxes further, sinking so far into the water that the suds touch his chin. “I was feeling a little under the weather after meeting with a client earlier yesterday. I thought it was just my body managing the exhaustion so I took some medication and went to bed. I woke up a few hours ago and couldn’t move, and well…”
“I’m the only person you know…?”
Or, Richard gets sick. At least he has a reliable part timer.

Summary
It's been 3 weeks since Richard returned from England. Everything is back to normal on the outside, but Seigi can't quite place his finger on was has changed in Richard. He's in denial of the effects of his actions on him, and Mr. Otomura's visit left an impression on him so much so it feels impossible now to ignore the stream of questions in his mind. Richard has changed, but not in a way Seigi expected.

Summary
Richard shook his head and spoke as though he was quoting something. “Please accept our sincerest apologies as we are closed today due to staff training.”
“Staff training?”
“Yes, or at least that is what the note I put on the door says.” Richard brought his other hand up to my waistband and swiftly popped the button open. “Consider this a learning opportunity for both of us.”

Summary
“I was told that the Housewarden of Pomefiore was beautiful, but I didn’t realize he was this beautiful.”
Silence. Richard’s eyes widened as Seigi’s face turned a bright red.
“A-Ah, I’m sorry!” he apologized with a bow. “I-I’ve only been here a month, so I apologize if I said something rude! Let’s go, Shimomura. We need to get back to the dorm.”
With that, Seigi grabbed the book and took off, his friend running after him. Richard watched them as they fled, a small smile on his face.
Nakata Seigi, he chuckled. Interesting.

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.
