Even after death, sometimes the body may experience spasms and similar reactions (I SAID SOMETIMES, I don't have enough understanding of the subject and yes I know from experience, if I could I wouldn't see it again). Btw, I hate this manga, I thought it was going to be something like seme going to save the uke, and it ended up horrible. I honestly have a really bad time reading this, it affects me a lot, that's why I avoid this type of reading, the extremely sad and suicidal ones too. IF someone feels similar to me, please don't read it, it won't do you any good. DO NOT READ BEFORE SEEING THE TAGS.
