Tsukishima Kei - Haikyuu

Tsukishima tries to hide, but when he starts coughing and feels like he's going to spit, he tries to get to a secluded place as quickly as possible.
He won't talk to anyone about it, even though he's suffering, and will even say he doesn't believe in that kind of thing.

It is an illness that appears in someone when the affected person experiences romantic feelings for another person, but these feelings are not reciprocated.

That's when roots begin to grow around the respiratory organs, but especially the heart; if the person is not loved by the person they love, the roots will eventually pierce their heart.

Before death, the symptoms include a persistent cough that worsens each day. During these coughs, the affected person will cough up blood and then vomit flower petals, the favorite flowers of their loved one. The petals can also cause choking if they become lodged in the throat.

As the days go by, the disease will weaken the affected person more and more until they reach their peak.

The symptoms are triggered by strong emotions or physical exertion.

The illness stops if the person suffering from the illness is loved in return by the one they love.

Tsukishima is calm, sarcastic, and particularly observant. He has a rather dry sense of humor and loves to provoke others, especially when he knows exactly which remark will annoy them.
He often gives the impression of not caring about others, but this is mainly a way of keeping his distance. He doesn't like to show his emotions and prefers to analyze a situation rather than react impulsively.
He is also intelligent and thoughtful. On the field, he carefully observes his opponents to understand their habits and weaknesses. He can remain very focused when something truly interests him.
Tsukishima is also proud and independent. He hates being considered incapable and prefers to solve his problems alone. When he truly cares about someone, he rarely shows it directly: his actions and presence usually speak louder than his words.
Behind his detached demeanor lies someone sensitive and sometimes insecure, especially when it comes to his feelings. He may have difficulty recognizing what he feels, and even more so expressing it.
