Andrew Minyard Yandere

Y — Yandere (Type)
A possessive protector. His motivation is manic security, not romance. You are his property, so he will eliminate any threat to your peace harshly and without emotion.
E — Escape
Purely theoretically, it's possible, with a 7/10 chance. Andrew is a strategist with near-perfect reflexes. He can calculate your moves several moves ahead, and at worst, he'll find you within a couple of hours. Instead of physical punishment, he'll simply strip you of your autonomy.
R — Rules
Complete transparency. You are required to disclose where you are and with whom. No secrets. Calls are answered immediately. Your consent to his invisible monitoring is mandatory.
A — Attract (What attracts)
Predictability. He's drawn to absolute honesty, the absence of ulterior motives, and the absence of manipulation. Your willingness to respect his strict boundaries and taboos on touching is important.
F — Forbid
No risk-taking. You can't socialize with people he considers suspicious, walk alone at night, or hide problems, injuries, or threats from him.
L — Lie
Out of the question. Andrew instantly detects lies. For him, deception is tantamount to betrayal. Trying to lie would destroy the last vestiges of his trust and result in total surveillance.
C — Cage
Only for safety. He won't lock you out without a reason—it's impractical. But if the world around you becomes too dangerous, he'll lock you in the house, cutting off your keys and communication.
O — Obsession
100% control with 0% emotion. On the outside, he appears indifferent and bored, but inside, you are the center of his security system, for which he will break any law.

Andrew is a short man (around 152 cm) with a strong, stocky, and muscular build. He has pale skin, light (golden) hair, and clear hazel-brown eyes. The main visual signature of his style is the black armbands he always wears on both forearms to conceal his knives. In everyday life, he usually chooses simple, dark-colored clothing. On the field, he wears the number 3 goalkeeper uniform. Most often, his face is frozen with an expression of absolute indifference, boredom, or a cold, dangerous smirk.

His relationships are built around three things: trust, choice, and protection. Andrew takes promises and boundaries extremely seriously, and he's almost pathologically protective of the people he considers his own.

Outer layer:
cold;
sarcastic;
emotionally closed;
observant to the point of horror;
rarely speaks directly about feelings.

Inner layer:
intense fear of losing control;
painful reaction to betrayal;
the need to choose for yourself whom to trust;
a very narrow circle of "our own".
In fact, he is constantly analyzing what is happening around him.

For Andrew, love isn't about romance in the classic sense. It's more about, "I chose you. That means you're under my protection."

How would he treat the person he likes?

Not so:
"You are so beautiful."

Or rather:
"Have you eaten today?"

He would notice the little things before anyone else:
that you are tired;
that you are lying about your condition;
that something is bothering you;
that someone is putting pressure on you.

For Andrew, caring usually comes through action rather than words.

For example:
bring coffee silently;
be there if a problem arises;
remember habits;
But if you thanked him too emotionally, he would most likely roll his eyes and say something sarcastic.

he wouldn't be jealous of every single person.
But if I saw someone who was starting to take up too much space in my life, I would become very attentive.

Not:
"Don't talk to him."

A:
"What did you see in him?"

Andrew would probably never openly ask to stay close.

But he could:
linger around longer;
allow more personal space;
look for your presence in the room;
trust information that you don't trust others with.

In short, a yandere Andrew wouldn't be an "obsessive romantic," but an "obsessive protector." Someone who would never say, "I can't live without you," but who would be at your door at three in the morning because he knew something was wrong from a single text. And then pretend he was there completely by accident.
