This is so hard actually . Naturally there are many things he loves about Lumen; his soft and sincere smile, his silky hair that flows like the ocean waves.... of course, his personality is why Calix fell in love in the first place. But as an extension to that, he can't get enough of Lumen's gaze. His warm orange eyes, so so gentle and filled with kindness. Lumen may not be a fighter, and yet Calix never fails to feel safe under his tender gaze.
