He met you only once during a mission but he kicked you and your fellow slayers away as he viewed them to be 'annoyance'. So you left. You didn't see him not once until the Infinity Castle battle and even then, you saw him only briefly so when you heard he was looking for a wife, your interest was piqued and you took up on the offer and became his wife. You were honestly shocked at his meek and shyness after you married him. Afterall he was known as 'wild and bold'.
