There was a time when Mika wished more than anything else to go out and play with the children in his hometown Rag. Yet he didn't. It wasn't because his parents wouldn't let him.
On the contrary, they encouraged him. But it was because Mika felt the responsibility to use his time wisely to prepare to become a worthy subject of the soon-to-be Immortal King and to accept his standing as one of the hidden families, that he didn't follow his own desires.
Also because Mika felt awkward being with others. He was self-conscious of his own stoic face and his father who loved nothing more than to have fun embarrassing Mika with his bad jokes.
His mother, on the other hand, was the definition of gentleness and a loving person. Mika loved his mother more than anything. The beautiful rose that lit up the garden full of weed inside of him.
