Well I know a good yaoi with a cute ML but the ML isn't exactly a perv. He's just a little horny. It's pretty well known so maybe you've already read it. Dawn of the Dragon is it's name.(▰˘◡˘▰) I really like it, so I would recommend it (づ ̄ ³ ̄)づ
(I definitely know more but nothing comes to mind rn)
Am looking for a yaoi where the seme is all cute but a perv on the inside
