I've actually read this manhua twice, not because it was particularly memorable or good plot wise but because i wanted to confirm if it was as fucked up as a remembered it and oh boy it was even more fucked the second time around. The plot is generic and sets everything up nicely, then in comes the gang rape violence sexual assault and abuse, it is pretty heavy and actually triggered me more than killing stalking if you could believe that... which i was surprised by myself. go give it a read i won't spoil you too much just beware of all the triggers and remember this isn't a love story stop.

So if you've been reading yaoi manga for a while now then you already know what this is, but if you don't then you've probably heard it from the web. It is pretty fucked up as obviously it is gonna be i mean seriously, tbh i didn't really enjoy it and i'm not the biggest fan of this author... Em Harada's work suits me more, if you wanna get into my head go read their works.
