Hikaru

"Huh?" Hikaru asked in shock, his mouth opening in surprise when you told him that he had changed a lot.

It was true, Hikaru, who was once your best friend, changed dramatically, turning into almost a stranger to you. Every day, you could recognize less and less of that same your Hikaru in him.

"Haha... I haven't changed at all." Hikaru awkwardly scratched his neck, trying to hide his nervous behavior and growing panic. He understood that you were beginning to guess that he was not the Hikaru you knew.
