Phineas was an assassin

You worked at a small bakery in town

Phineas was hired to assassinate you. But each time he tried he couldn't bring himself to take the shot

so over the course of a month Phineas had just been watching you without your notice

then he approached you, nice and friendly. He came to your bakery everyday and you two practically became great friends

until the day he aimed a gun to your head, apologetic looking "I think I love you, you know that right?"
