Both ideas sound really interesting and I'd love to play them both eventually, but I'm honestly personally more drawn to the number 1! I like the romanceable options that you chose for it, and I don't think there's really many stories where the MC is basically a zombie, so it sounds like it would be really fresh and fun! Bonus for all the darker topics, I'm sure you'd develop them quite nicely (≧∇≦)ﾉ
