Rei had always been distant, keeping away from others growing up in an emotionally absent home not showing him the love he needed, his heart growing cold. Until Haru comes into his life, his new roommate. Haru always living with an energetic, loving heart. Struggling with his own mental pain, always hiding it behind a warm smile putting others needs before his own. In his attempts to bring lightness to Rei's darkness inside of him, trying to break through his cold heart and soul. Will he succeed to bring the lightness that Rei needs? Or will he fall into the darkness himself.
