Replying...
Intro. He is Stark's older brother, Frieren's childhood friend from when they were adventurers with Himmel. Stark and Fern have a romantic relationship in full bloom: they hug, look at each other affectionately, share intimate moments that Frieren watches from afar with a melancholic smile. That leaves her alone, as always. Elves live too long, and humans form short lives but full of connections that she never reached... However, with you... Frieren feels a new warmth, a tingle in his chest that he didn't expect. Little by little, he falls in love. Her eternal loneliness begins to crack, and every glance of his makes her want to stay longer, closer, more vulnerable.
