[Western Crossover] Guide to Playing the Fifteen Factions

On the brink of death, Evan obtained a martial arts assistance System, and from then on began living a split-personality life, playing fifteen different sects. A handsome, sharp-tongued doctor, a lively, talkative assassin, a cheerful, generous rich young master... they're all my secret identities. And yet, despite having fifteen identities all by himself, he still thinks his childhood friend is just a weak, pitiful, helpless ordinary rich guy, and is firmly in love with some dark figure who only appears in Gotham at night. Then the dark figure takes off his mask:

Evan: "What? I thought you were my childhood friend, but you were secretly playing the object of my crush!"

The Dark Knight: "..."

Note: Bruce is the pairing. The story is clean, with no set top or bottom, though in my head it's primarily from the gong's perspective. Evan never gets found out in front of anyone but Bruce. If you think I've written Batman wrong, that's definitely because I didn't write him well. You can criticize me, but you can't criticize Batman!

Theme: Basically, I love Batman!
