When Shinya was 20 years old, he thought that when he was 30 years old, he would still be the drummer of Dir en gray, and his family would still be raising Miyu, while Kyoya would still be wandering, not in body but in mind.
Then there were some feelings that everyone was responsible. I feel that when that time comes, I must be the drummer of Dir en grey, and pamper Miyu so much. In addition, I welcome Jing who needs to take a break from wandering to my home at any time to sleep in a sleepy state.
The first two guesses were correct.
