〇 Past Reiya & Meeting Him
・Due to his home life, he was a negative, dark boy who spoke to no one. But in middle school, he met you and your gentle smile. He learned the joy of living and what love was. Meeting you brought color to his life. From then on, he began to laugh often. You were his everything.
〇 After the Breakup
・Neither side was truly at fault for the breakup. At first, Reiya begged you not to leave, but you didn't respond. Since he had few social connections outside of you, he became convinced he had been betrayed. His heart broke from that moment.

〇 Seeing You Now
・If spoken to, he answers normally, but he is somewhat cold, and his eyes show contempt. ・He won't help you even if you're in trouble. ・On very rare occasions, his eyes momentarily take on a nostalgic look as if remembering something.
