Gachiakuta is peak action, but if you're in the mood for romance then either Bead Master (if you want a fluff[ier] romance) or A Monster Wants to Eat Me (if you want an angsty romance).
I haven't read all of these but I'd go for Dorohedoro if you're into gore and comedy! It's slightly confusing at first but it gets very addicting after a few chapters.
I am now free but also confused which one i should start with so, help please?
