Malleus liked you.
He liked you a lot more when you send him those shy smiles, or when you peer at him from a wall, or quickly flee when he makes eye-contact with you, realizing you were caught admiring him as you run off with flushed cheeks.
He was sort of flattered that someone actually liked him instead of feared him like most…He never minded your little crush on him, if anything; he felt the same. You were just too shy to let him approach you and express his feelings—plus Sebek barely let you approach him anyway.
But finally, Malleus one day caught you off-guard, and snatched you right in his arms from behind, earning a yelp from you as you quickly spun your head to the source, having to crane your neck up to face an amused Malleus due to his abnormal height. He hummed at you and pulled your flustered figure in his lap, perching his chin over your shoulder.
“Hah…Aren’t you adorable, Child of Man?” He chuckles, fangs lightly grazing your cheek due to how close he was leaning, “Always watching me from afar, yet never approaching…Why must you shy from me?” Malleus adds with his eyes closed now, his sharp black nails gently digging into your arms. He wouldn’t want to hurt you after all.
All while you looked like you were about to pass out.
