So I came across this manga around three gears ago that had a high school laboratory setting and two guys (this was most likely a yaoi manga) needed semen to be put under the microscope or smth??? So one of the guys volunteered to give his? It's been living in my head rent free because I didn't get to finish it. I think it only had about two chapters out when I found it so if you think you know this story help a homie out! Tysm!!!
I couldn't get into the story because of him but I still finished this just to see if he would somehow redeem (?) himself......he didn't.
