He wondered when it happened.
When did the broad, evil grin at this face, appearing after he punched his opponent's face out of sight, start to affect Furuichi so much. He couldn't avoid the wave of astonishment that rushed over him, leaving a strong impression of pride for his best friend's unwavering, iron self-confidence.
But it also seemed to stirr some other feelings in him, emotions that were both far more intensive and alarming than anything else; it was the feeling of admiration and the need of eternal loyality to this man, the wish to follow him forever.
Maybe, when he saw him the first time getting so happy while burying some nasty dudes in the ground, he already felt it.
Unfortunally, as the years passed by, it became worse. Oga seemed to control his time, his mind, his life. No chance of breaking this connection was given. It was a curse and a blessing at the same time.
Should he blame the hormones? A silly thought, it was just an excuse to run away from the reality. He didn't want to realize that he already fell deep down the abyss of love. He wouldn't never admitt it. He was a man after all and shouldn't have this kind of a relationship.
Although, the hope for mutuality would still stay.
