OMFG THANK YOU BLESS YOUR HEART
Classic request, but can someone recommend me a BL (shounen ai, or yaoi) where the seme/ml is toxic? I would prefer there be like a chasing arc, haha. I've read so much so if you can give me your deep-cuts, something you think I may have not read! Thank you! (≧∀≦)
(P.S if you also have toxic yuri, leave it down below!)
