Maybe the title changes as per the change of translators or scanlation team? Not sure tho but you know right, how a sentence of a certain language can have more than one explanations in another language...I remember another bl manhwa with two English names (What lies at the end and At the end of the road)

Why does this have different names in different places? Like, the title is “papa is a bride” but then at the end of this last chapter (at the bottom) it was “papa is a gay”? Why do some mangas/ webtoons do this?
(I’m not criticising I’m just curious)
