[Bungo Stray Dogs Crossover] A Love Triangle Between Secret Identities and Lovers

Freelancer Takeshita Rin has recently run into a problem. He has a childhood friend, someone he has known since they were little. They weathered all kinds of hardships together, only to be torn apart by evil forces (□□???). Years later, they meet again, and they still understand each other without a word (something doesn't seem right...) He has a secret identity, courtesy of the System, and it's incredibly useful. Perfect for killing and arson (scratch that), or just everyday life and travel. Whenever he gets into trouble and can't explain himself, he can happily pin the blame on his secret identity. These should both be things to be happy about... They really should... So, Chuuya, why do you always have a problem with my secret identity?! Some □□ executive (looking thoroughly displeased): Hey, stay away from that guy! Takeshita Rin (as his secret identity): … But that's still me, isn't it? A secret-identity story. The protagonist may (but not necessarily) have more than one secret identity. A (fake) love triangle is in the works. Planned for a future release, waiting in line. Theme: Finding you among millions of people.
