there is some romance with the characters you meet, and bonds with keep developing with time, but it's not a classic VN or dating sim where you choose a mate or even marry, you can get closer and fool around with most as the story progresses, if you wish to, something more... official might come later on, who knows.

Also Caro just reworked the battle system, but this is the battle strategy i wrote in the guide back then for the headless knight:

"HP potions barely heal more than this ruthless beast deals, binding up should be way more efficient after the rework, if you have MP potions to spare, so either attack or start with a holy fist and use your recharge turns to bind up, drink a potion or defend if your skills are on cooldown, the fight used to be way harder when the sword couldn’t be upgraded and bind up was useless."
