My perfect yandere!

Never have I imagined that my first relationship would come this abruptly. Some days after I lost my most precious people in life, another person appeared who surprisingly became my most treasured being. I love and adore her but not compared to how much she does. It's not like my love is a fleeting cloud. No-no-no. I love her very much but she...

"Kayo. Have you done something with Saki sensei?" I asked worriedly as our homeroom teacher suddenly disappeared just a day after she gave me extra classes.
I had a clear doubt about the culprit so I asked her directly.

"Nothing much. I just sent her to a faraway place where she won't be able to see my love again in her life". I gasped.
" You dont mean..."
"Ah, I didn't kill her. Just sent her to another nation with a better job and she must be happy there." She gave me a smile which made me relaxed at the same time mesmerized.

As one can see, my girlfriend(wife), is a yandere who refrains herself just because of the marriage promise I have given her. Even with her dangerous behavior...I love her and always will until death does us apart.
