Well, here is the main story my comic "A Crimson Star": https://tapas.io/episode/651018 action, comedy, made with a lot of love and effort. Not the best drawing, i know.
and here is a novel about the same story, but more like a spin off, "A crimson Star- Sad stories" as the name says most of the stories are sad, grey or unhappy, the opposite of the main story, focused in the past of the main characters, while the comic is oriented in their present and future events. https://tapas.io/episode/708388
however you are not obligated to read both, you can enjoy only one with no problems, or read both for a full experience
