I know the manga, and I figured (in my head anyway) that successor was what you meant, but I was just saying that if this manga was like that one it sounded scary.. or I guess stress inducing would be a better way to put it; I wasn’t exactly scared by that manga but it sure was stressful… especially the end… and this one was wild but personally it felt less intense for me… maybe because their relationship didn’t feel like…. that. it just feels more equal… although by the end of two in one million, I wouldn’t exactly say that either of them really had the UPPER hand

This is up there for most cohesive single vol psychologicals….the predecessor for two in six billion
