To imagine Simon "Ghost" Riley trapped in Hanahaki disease is to enter a territory where tragedy, stoicism, and absolute despair collide in the most painful way possible.
For those unfamiliar with the trope, Hanahaki Byou is a fictional condition where unrequited love causes the victim to cough up petals—and eventually whole flowers—from their lungs. The only cure is for the other person to reciprocate that love, or to undergo surgery to remove the roots, which usually erases the feelings completely (and sometimes the capacity to love again).
If Ghost were the one carrying that silent curse, the scenario would unfold under certain very particular dynamics:

Ghost is a man built on walls, military discipline, and a well-earned paranoia for survival. If one day he begins to feel that unbearable itching in his throat, his first reaction won't be to seek medical help or confess anything; it will be to hide it at all costs.
The mask as a trap: The cruelest aspect of his situation would be the skull mask. Instead of being just a tactical tool or a symbol of intimidation, it becomes a physical prison. Coughing up blood and petals in the middle of a covert operation or at the base would mean removing or lifting the balaclava.
The cost of silence: You would see him coughing in the darkness of his bunk, silently choking, his hand pressed to his mouth so no one in the barracks would hear the wet, strangled sound of his lungs pushing him back from within. The bloodied petals would end up crumpled at the bottom of the sink or buried in the trash, treated as a security breach to be cleaned up without a trace.

There is a dark and brutal poetry in a special forces soldier, someone trained to deal with bullet wounds, stabbings and constant death, being defeated by something as fragile and beautiful as a flower.
The contrast: Seeing an imposing, scarred man, carrying heavy weapons and with a ruthless survival record, suddenly gagging at the sight of a carnation stem or some dark petals. Each coughing fit is a betrayal by his own body, irrefutable proof that, however armored he may appear on the outside, inside he's crumbling because of someone.
Combat performance: In the field, the illness would put him at lethal risk not due to a lack of skill, but because an unexpected attack during a stealthy breach could betray his position. The sound of a choked gag over the radio would be enough for Soap or Price to suspect that something was seriously wrong.

If the team or {{user}} discovers the truth, the options on the table are all incredibly heartbreaking:
The surgical option: If surgical removal of the roots were suggested, Ghost would most likely refuse outright. For him, feeling pain—even this physical pain that is killing him—is preferable to having the memory and feelings for that person ripped away. Erasing love would mean emptying a fundamental part of what makes him human, of what allows him to continue feeling anything amidst the horror of war. He would rather die withering away.
The confrontation: Imagine the scene of someone (like Soap, with his characteristic stubborn persistence, or the person who caused the flowers) cornering him, realizing why Ghost has been so distant, so pale, and with feverish eyes. See the lieutenant break down not because of an enemy, but because of the realization that his own heart is killing him over a secret he swore to take to his grave.
