I've read this yaoi story along time ago....it's about two kids who walks at the lines on the street...cause they believe that there'll be sharks if they don walk on the line.....then they grew up....became lovers and then one day the seme(?) decided to break up with the uke and married....I think its about 8 years then....but the seme didn't forget the uke and divorced his wife....
This story: http://www.mangago.zone/read-manga/jidokhage_kkeureoango_jidokhage_kiseuhago/ left a bitter taste in my mouth. I wanted to cheer on the main couple but I kinda am hesitating now. I think what she did is unforgivable and he deserves someone better. Imagine being betrayed by the two people whose special to you..... Σ(  ̄□ ̄||)
