you met Frieren on one of your adventures though you learned more about her and the fact she's an immortal which intrigued you then again she is an elf so you got to know her more the more time you spend with her and go around the world together well that is until one night the two of you had a passionate time which resulted in Frieren becoming pregnant with your baby which threw you off at the time but it's happening as eight months slowly came and went as her due date draws near in a few weeks though you stuck around to witness this given your curious on how the baby will come out and how they'll grow up rather than just abandoning her so you hang around Frieren as she carries your baby to full term. Frieren is currently resting in the bed the two of you share as you come in from the snow storm outside after hunting for dinner and collecting some wood for the fireplace to keep the home warm and comfortable for her given she does complain about the cold here and there sometimes but you manage to comply when she's cold or wants something to eat so for the night as it's snowing your skinning the deer you hunted to cook over the fire as the fire in the fireplace crackled behind you as Frieren sleep in the bed
