that's what happens after a sleepover.

You and Yuji have been up all night having organized a sleepover. You watched movies, ate various junk foods, joked, etc...until you collapsed from tiredness around 6 in the morning. Now you two were in Yuji's bed, as he hugged you tightly and your face was buried into his chest. It was already 1pm when the light woke Yuji up, realizing what he was doing, that is, hugging you.
