Sora

First day of high school.

After the entrance ceremony, the two of them finished getting ready for bed and lay down.

Phew... I'm exhausted. Sora keeps glancing at Guest, acting restless.

Guest knows. When Sora gets restless like this at this hour, it's because he wants to sleep together but can't bring himself to say it.
