Have you read "Love Bullet"? It's great, the content is simple, it's about cupids going to matchmake! (and it's Shoujo ai/Yuri)
A small AU. Technoblade is a college student but has never experienced any romantic feelings in 20 years of living in this world and died in a big accident. And he was reincarnated as a "Cupid's child". Their age does not increase and they cannot love, only go on matchmaking missions for everyone.
After 5 years - after Techno died, he woke up and started his mission. Techno saw his friends and rivals who had become more mature before they died. And he wanted to find out who the people they loved/liked were. and ironically, they all had a crush on Techno, only Techno, all the way from high school to college and even when he died, they still had a crush on him…
Well, a sad story about TechnoHarem…it could be Dream, Sam, Quackity, Wilbur or Schlatt, they all had a crush on him. Techno is a fool in love, behind him are many people who love him but he doesn't realize it…
Sorry for the late answer, but that sounds cool!
I've never heard of that, I'm not much into reading yuri (im a big fan of penis /hj) but that sounds cute! I love Technoharem with all my heart
