Lucifer the Butler - Devilgram
"He must feel relieved now."
The next day, Lucifer wakes MC and offers them their morning tea, but almost immediately something happens again. It turns out that his brothers had another chain of accidents which wrecked the dining room. The breakfast turned out to be inedible too. Asmodeus expects Lucifer to start yelling at them, but Lucifer assigns tasks to them to clean up the mess instead. In the evening, Lucifer explains that he decided that he won't be cleaning up after his brothers anymore and he'll treat his brothers with the same kindness that MC showed when he was failing his duties. As a result, Lucifer no longer has to cover up for their mistakes and has time to fulfill MC's wishes - they have a choice to ask him for a kiss. If they do, Lucifer wants this duty to be assigned to him only.
