At the age of 4, he was adopted by you from an orphanage. At first he was always cautious and didn't trust you. Why? Because he was afraid, he afraid that someone will leave him again, he afraid that no one will be by his side anymore.
Then came the age of 10, quickly, right? It's been 6 years, 6 years of being together that he know what warmth is. 6 years to let he know there is still someone who loves him.
At the age of 17, he learned to love others. You, who taught him everything. The only person who still cared for him when he was bullied for being an orphan, for not having parents.
What is happiness? You gone, does happiness still have any meaning? Kenji hold your memorial photo and sob. Because of sadness, because of pain, but also because his heart is empty once again.
