What gets L's engine revving, if you know what I mean? 👀 Both generally and things his crush does. I feel like it's weird or unexpected (throwback to him chowing down on that banana peel totally not out of frustration during Misa's commercial ahem)
Mental/Cognitive
To him, competition is intimacy, so someone who can meet him blow for blow in analysis and timing or even outmaneuver him - even once - ignites a rare dopamine spike. Someone who questions his deductions, offers new perspectives, or reaches the same conclusions he does but faster, would catch his attention fast.
When someone is unpredictable, yet internally consistent. He doesn’t like impulsivity for chaos's sake, but someone he can’t fully predict catches his attention. So someone who lights up for one plushie but expresses total disinterest another, or someone who randomly blurts out questions that seem to come from nowhere but actually make sense when they explain it.
Someone who lives in implication truly undoes him. He doesn’t trust overt declarations. Implication is his native language. So, someone who communicates in glances, tone, and leaves things hanging mid-sentence forces him to stay attuned in a way that sustains a low-grade tension that he reads as attraction long before he’ll admit it.
Catching someone in a lie is like his kryptonite. When someone baits a liar into confession or better yet, contradicting themselves is deeply arousing to him. It’s the kind of subtle manipulation he considers art. Especially if they don’t gloat and simply act on the information they obtained, he’s smitten. It registers as competence with emotional restraint - his favourite combination.
Emotional
Emotional restraint. He finds emotional transparency comforting in the sense that he doesn’t have to guess what someone is feeling, but he doesn’t find it compelling. What really draws him in is the concept that something is just out reach. So, someone who is rational and restrained with occasional glimpses of deep emotion that are kept under tight control really gets to him.
The moment restraint cracks. Seeing someone, who’s usually composed, slip lights him up because he feels it’s earned rather than given freely.
Personality
Someone who isn’t a push over. Someone who holds their ground against him, or others, without being reckless or defiant for defiance sake.
Creativity and resourcefulness, especially if it reveals an underlying quality. For example someone who stabs the lid of a pickle jar instead of asking for help to open it would register as intelligent, creative, resourceful, and telling of their independence to him.
Sensory
Someone who subtly makes him more aware of his own body and reactions - eye contact, heart rate - that subtle disruption, the feeling the roles are reversed and he’s the one being observed now, is one of the first things that makes him register his attention towards them as lust.
His detachment means he sometimes forgets his own physical presence so being forced back into embodiment, would be both uncomfortable and addictive.
Dialect
The way they talk. He locks onto word choice and tone more than he lets on.
Someone who is careful with their wording. Word choice matters in terms of how a message is perceived and that sense that every word has a purpose is a hook for him.
Physically
The way their hair flows, bounces, and cascades - especially when they run their hand through their hair
Subtle Intimacy
When someone unconsciously begins to mirror him in mannerism, internal reasoning, expression, or dialect. It registers as unconscious intimacy.
Someone who can hold eye contact with him without judgement or curiosity, or feeling intimidated by him.
Mannerisms
He’s a big mannerisms guy. The way a person types, flips a page, stirs tea.
The way they hold things, delicately, gentle, almost clinically.
Handwriting. Especially someone who writes quickly and heavy handed, but never loses the eloquence.
Facial expressions. Especially mildly suggestive ones, like the way they bite their lip or nail when they’re concentrating, or the way a fleeting tug of a smirk when their two steps ahead and know something they’re not quite saying - just letting it be known that they know something. Those expressions, to him, carry intelligence, irony, and withheld amusement and suggest that they’re operating several layers deep.
The way they sit, especially if defies social norms but radiates ease, comfort with themselves, and confidence.
The way they walk. Especially if it’s graceful, never in a hurry, suggestive that they’re deliberate and choosing their timing.
The way they communicate with their eyes. He instinctively responds to subtle side glances that carry the weight of irony, curiosity, fascination, attraction, or warning.
