After reading this I actually felt the urge to check the year, just to see if I wasn't back in the 2000s again. From the artstyle, overall narrative, from the rapid development from blackmail dubcon to love, it truly felt like a 2000s yaoi LOL
I read your comment and checked when the maga was released...it was realised in 2002
? it was released in 2018. Just check backupdates.
Oh sorry I read too fast on manga go
Welcome to old yaoi trope I guess
