Promise

That was a long time ago. In the countryside where I went to escape from studying for exams, I met Nagisa, who was like a sunflower. The summer vacation I spent with her was an eternal time that gave me light and courage in my life. Nagisa, I will never forget the promise I made to you that summer. ___ This is Yuki Suetsugu's masterpiece, depicting the sad memories hidden in her heart.
