Bassena rarely cried.
He used to be a crybaby when his mother was still there to soothe him. He cried a lot during the hellish training period leading to his awakening. And then he stopped, because crying only made him beaten up even more.
After that, he never cried again. The emotions that used to trigger his tear glands shifted to anger instead, and that was how he became a wild beast that Han Joon and Radia needed to tame in the academy.
But he never cried again, even when everything felt so painful. He did not cry again even in front of his mother's grave.
He did not cry again until he met Zein.
It was when he found out what happened to Zein during the kidnapping. And again, when Zein finally, for the first time, uttered that magic word; love. That he loved Bassena.
The tears came again when he heard the same word, in the same place, uttered with the same expression; serene and sincere.
