Understanding the Omega 1

Sangcheol stares at the ringing phone vibrating on the side table, wondering if he should answer it or wake the sleeping omega instead. But Haneul had only been sleeping for a few minutes. Or hours. And he needs to rest to recover. Unable to decide, Sangcheol hops lightly, gritting his teeth before grabbing the phone and softly answers, "Yoo Haneul's phone. This is his friend speaking."

"Good evening. Is Mr. Yoo Haneul available?"

"He's sleeping." Sangcheol looks at the omega, making sure his voice is not so loud that it bothers it other. Unfortunately, he notices that Haneul is moving around, trying to turn away from him; his face pained. Feeling sorry, Sangcheol makes his way towards the bathroom and leans against the wall before continuing, his voice low but clear, "Is there anything important? I can let him know."
