my sister read this a while back and from what i heard from her it was about this demon girl with the side bangs and the angels are kindda the antagonists that try to disrupt her peaceful living arrangements with the human boy. if it is not so, pls pardon my wastedness.
^that can be the summary for the first 9 volumes (out of 10 )
well, i can vaguely understand the ending from the series description on MU but there are details that are not clear like how there is nothing in heaven(perhaps only some of the angels got tangled in MC's dream?) or that last line "but you didn't eat the egg princess"
