The day I reunited with my former boyfriend from a few years ago, I couldn't even bring myself to look my son Naoki in the eye. My relationship with him was supposed to have been temporary, yet standing before him again, my heart trembled unpredictably. When Naoki confronted me in that moment, I felt utterly guilty. What happened back then can't be dismissed as a simple misunderstanding. There's no excuse I can make now. I've left something behind between him and Naoki.
