Maid is best girl and its the reason for him being there.
But, since when? The Meido has barely any screen time and suddenly there is a scene implying she has been giving morning kiss everyday?
Or, is this that SOP-thingy. So, MC and all the girls receive a morning kiss everyday from their own respective maids?
Does the MC not like puffy or something?
Because harem rules, every remotely important girl must eventually fall in love with the MC, doesn't matter how stupid the reason is, actually the more you make the viewer confused the better it is.
