I can't remeber this series name but its BL. It's Zombie themed and I believe it's about 2 childhood friends. I THINK seme had light hair and uke had black hair. Seme gets bitten and runs away to avoid Turning into a zombie and gets saved by a group who used a drug on him as a test. In doing so he didn't become a zombie.
