Love Rivalry: Devil vs Faunus (Xenovia x Male Reader x Blake)

(I wanna rewrite the last book and besides this works better for me) In Beacon Academy there's 2 girls who rarely show any emotions and both aren't human, Xenovia Quarta a secret Devil knight who served under Rias Gremory felt lost for the 2nd time in her life with how her heart felt around Issei the Red Dragon Emperor. For once she felt heartbroken by how the females in her club was around Issei and she felt like he wouldn't felt the same way she feels for him and all she missed was feeling loved, the other one was a different story. Blake Belladonna a secret Cat Faunus who is a member of team RWBY and follow the lead of Ruby Rose, unlike anyone else she kept her emotions near the down low and act a bit emotionless mostly cause she was hiding the fact she felt lonely and not by having friends but having someone special in her life since she never felt the love she once felt before and wished she could feel the same love in her novel. What should happen if both secret girls met a boy, a human boy and somehow felt the same for him in which they never felt before. And that was love, what would happen if both girls learn that the other has feelings for the same guy especially a human. Who would win this rival the sexy blue knight or the purple ninja cat girl.
