Honestly, 'Fertile' sounds badass and kind of eerie/haunting which is good for like a devastatingly sweet kind of story! But 'Life goes on' would be perfect for a deep, and emotional story that's also a fun Feel Good kinda story, you know? A little less formal and more free I guess? But both definitely sound amazing and I look forward to reading it!
I don't know of any of this makes sense bc I don't what you have in mind and what's your story about lol but that the vibe I get :))
