After a few days, you began to realise how tired Lyney was getting. You asked him about his sleep schedule and he said it was fine. And yet, whenever you'd message him at night, no matter what the time, he'd respond.

At some point, you were both in the middle of lesson and Lyney's head fell onto your shoulder, he was fast asleep.

As you shifted he didn't even wake up? He just fell down and his head landed on your lap. The lesson continued and he remained asleep.
