i respect ya opinion. and yes that specific cunnilingus scene is indeed a breaking point. but again, in my opinion it's not enough, again my opinion, it's not a fact nor a claim to be one. i would classify it as maybe low yuri (jeah i know, we don't have that tag). it's a bit like those comics that have the low beastiality tag on it. a dog licks a girls pussy and therefore gets the low beastiality tag on exhentai. but what happens if you don't have that tag, would you consider giving this comic the full fledged beastiality tag? yet, if the mods say, that due to the scene the tag has to be implemented then i'm totally fine with it. the reason makes sense, it'S their way of handling tags anyway, end of story. and i only cracked up this topic about tags, is, that in the past some tags led to misleading searches. i still remember that one mod classified a game with a pregnancy tag due to a female side character appearing in the game in a pregnant state. she only talks a few sentences with the MC, doesn't have any scenes and disappears later on. ya can't tell me that this is enough to give a game that tag, or... or??? if you want to you can see my opinion as a foolproof way, or overexaggerated way, to 100% say, without doubt, that the game definitely needs that tag.
ps: you can search tags in the latest update section. there you can filter games by using tags. any game with that specific tag will then be shown. pretty neat function.
