Does anybody know what's going on?

Has anybody been able to figure out what's happening in this series I'm at the end of 6:00 and I'm just as clueless as can be.. the subtitles are in English but it's just random words put together that don't mean anything and he she I them you all mean the same thing and what they're saying I can't figure out what the translator is trying to do is just nonsensical is all I can get out of it so it's hard to figure out what's happening in the series without knowing what the words mean cuz there sure is not what they're putting down.

What is going on?

I'm not sure what this BL is about or even if it is a BL there's a lot of girls involved. I can't keep track of who's who and who the main characters are. I'm sure they went to a lot of work to make this thing but I just don't understand it or know where we're headed with it. I think we're gone back in time to covid.
