Love at First Sight

I'm new to this, and this is a short story of only a few tens of thousands of words. Feel free to take a look. A fated bond, a sincere affection. On a bitterly cold winter night years ago, snow swirling in the wind, you led me out of that freezing hell... The everyday life of a master and disciple cultivating immortality and fighting monsters. It's all made up, so feel free to read at your leisure and pass the time. A clean BL story. If it's not your thing, please move along. Premise:
