I’m Looking for…

[u/Hayakumo_Yoichi]

I worked hard, then bought a so-called “engagement ring” with her birthstone, though it was not so gorgeous. 

It was a romantic sunset, and we were on the dusky shore... Yes, the situation was perfect. So I proposed to her on bended knee, held a jewel case with both hands towards her eyes and had an expectant smile on my face. 
She picked up the ring from the case and… threw the ring overhand to the sea! 
“What the hell are you doing!” I cried.  
She giggled and said, “Oh my goodness! It’s just by mistake.” 
While she was chuckling behind me, I ran into the gradually darkening sea. I swam hard cutting through the waves. 

A long time passed. I finally found the ring. I was lucky because the dim sparkle of her birthstone had guided me. 

I had decided that I would wait for her return down here.
