As soon as Yugi walked into his office, the atmosphere felt off. The usually cheerful boy was unusually quiet and his smile seemed like it could slip off at the drop of a pen. He momentarily stopped typing to study his boyfriend. His posture was off as well, shoulders more slumped. Yet, he didn't say anything to give away his emotions.
"Hey, Seto! How was your day?" Even his voice sounded somewhat off. Flatter in tone, perhaps? Kaiba wondered when he started noticing these small details about Yugi, though he didn't dwell on it long. He wasted no time getting to the point of the matter.
"What's wrong with you?"
Yugi's flimsy smile fell off his face and was replaced by a look of shock.
"What?"
Kaiba resisted an eye roll as he repeated himself.
"What's wrong with you, Yugi?"
"I- Nothing, Seto. Why would you think something's wrong?"
"Your whole demeanor has changed. I'd be a fool not to notice."
Yugi paused, pondering whether he should keep up his facade or be straight with him. Kaiba already knew that something was up. What would be the use of lying?
"It's… Nothing important, Seto. I've just had a bit of an off day and I don't feel the best."
Kaiba raised an eyebrow, studying him. However, no matter how hard he looked, he only found honesty in Yugi's eyes.
"...Come here." Was the surprisingly soft reply that Yugi got and he wasted no time in going over to Kaiba. He tilted his head slightly, confusion evident in his features.
"What is it?"
Kaiba gently grabbed Yugi and brought him into his lap, Yugi placing his hands on Kaiba's chest.
"Just relax with me." He said as he moved Yugi so that his head was resting on his chest. Yugi let out a smile at the steady beat of Kaiba's heart and said, "I love you." before closing his eyes. Kaiba smiled softly and pressed a kiss to the top of his head.
"And I you, Yugi."
The two just rested there, Yugi eventually falling asleep, and Kaiba taking a much needed break from his work.
