Boku wa Kimi o Hanasanai ~Gomennasai, Boku, Kare ga Suki~

I , Kinoyama Ren, since I was a child, I've admired my chilhood friend and neighbour Tazawa Haruki-kun. He is my first love and I still love him. But there's no way I can say that. He likes a girl. His love interest is a girl. But I am a man... So I keep those secret feelings inside my heart. I though I wouldn't say them in my life. Haruki started dating my older sister and they become a couple. One night, my feelings were exposed and were discovered by him. But Haruki-kun also loved me...
