One afternoon while in class, you were napping since you were just so exhausted from gaming all night.

When the afternoon sun shined on your face, it caused you to stir. However, Childe held a book over your face, blocking the sun.

He smiled softly as he saw you return to your slumber peacefully.

He'd be lying if he said he wasn't slightly attracted to you. So, he watched you nap for a few more seconds before turning to the front of the class for the rest of the lecture.
