>>90454500Blazblue was considered a dead IP. The gacha failed, the director left, no more games. nothing, zich nada.
I really love Blazblue, and one day i came across a (in retrospective) pretty mediocre fanfic of Tsubaki, a character defined by liking another boring character, falling in love with the MC. I loved it, even if it was shortlived because the author deleted her fanfiction profile.
This was years after we last had any news of the IP, yet the writer was still there. Blazblue never died because people still play and love it to this day.
Passion for a thing only dies when you let go of it, so i think that even if your oshi graduates or she leaves the internet, if you still have passion for her(or him) then things are gonna be alright.
