O Human Star is an engrossing, completed webcomic by Blue Delliquanti. It has robots, love, and heartbreak. It dives deeply into what it means to be human, what it means to grow up, and what it means to be your true self. It captured my full attention. It was a fixture on my phone browser and I went back to it every spare second I had until I finished. I would highly recommend reading it and also recommend that you act smarter than me and read it on a full sized screen.
Caution, there are a few minorly NSFW moments, but nothing too scandalous.
