Maple leaf

During the last long vacation of my student days, I stared intently at the countryside sea. As I became captivated by the sea displaying its various forms, evening arrived before I knew it. At that moment, the one who called out to me was a well-built "old man"... There may be BL elements to the degree that it might have a faint BL flavor? This is a short story that I excavated from a serialization on my personal website from about 10 years ago and have re-edited (the website no longer exists).
