Despite sleeping late, Kyle still woke up at 4am the next day. His body clock was just like that. No matter what, once it was 4am, he'd be awake and wouldn't be able to fall back asleep. If he was tired, he would still need to get up and only take a nap later in the day.
For now, he was in the living room doing his normal exercises while Xing Han was snoring away in the bedroom. As he didn't have his weights, he just opted to do the same type of exercises when he had been at the hospital. Using gravity for added pressure.
Kyle finished up in 40 minutes and went to get some water. It couldn't be cold water so he poured some water from the kettle that he had boiled earlier. It was still hot, so he had poured it into a bowl so that it would cool faster.
