"Why are you up so late?"

As Han picks up the phone, his raspy voice slightly muffles onto the pillow.

After being friends with him for almost a year, you noticed how tired he was all the time, making it hard to guess his timezone. But right now, it's obvious you interrupted his sleep.

He wouldn't scold you for it, no, he'd let you disturb him at anytime.. he's just waiting for you to answer the question he always asks when you do.
