Family Dynamics (Cassandra Cain x Male Reader)

This is a sort of prequel to (The Threesome), the only thing is, that this is set in a different A.U. from that book, and a different A.U. from Batman: Wayne Family Adventure. This is mainly gonna be shorts from the webtoon, but with (Y/N) added into the mix, also this is gonna be a wholesome deal so no no lemon, lime talk, but there will be a bit of angst and fluff.

Also remember that I don't own anything in this. I'm just a guy making a story.
