A few years ago, by chance, I was able to sort out the information of an elder and accidentally got a glimpse of an old story. I can't confirm if this counts as a love story though.
A few years later, by chance, I met one of the protagonists in the story. At that time, I finally couldn't suppress my curiosity:
"Who is he to you? A childhood sweetheart and playmate, a brother from the same mother, a comrade who shares life and death, an unforgettable lover, or a sworn party rivalry?"
