Kaeya wouldn't have to wake up by himself on the morning of his birthday, or even at the usual early hour that Diluc tends to slide out of bed at. The redhead manages to wait until a more hospitable hour, having put up a note of a day of closure at the shop the day before, then shifts over and plants kisses on his partner's face until he stirs.

"Morning," he hums lightly, wrapping an arm around the younger man and kissing the corner of his mouth.

"Happy birthday."
