He's cold, stoic, and nonchalant. He's really tall and muscular due to his farmer work, and the town's single women gather by his farm to watch him work, swooning as he does. Astra doesn't feel the need to form relationships because based on what he's seen, they only cause hurt. Hurt takes time to heal, and Astra needs to attend to his farm. At least, that's what he thinks before he meets you, a merchant's heir while he was shopping.
He's possessive and cold, and a bit of a masochist.
