HBAD-126 - Arrogant female teacher, bullied by student after being blackmailed

In this series, the male lead is such a piece of trash that the female lead's haughtiness doesn't even come across as haughty. This time, the female teacher is serious, uptight, and wears glasses without ever cracking a smile. She gives off the vibe of a class representative or a member of the disciplinary committee. She seemed like the type to be strict and righteous with herself and others, but the way her true nature as a hardcore masochist—who actually wants to be violated while being watched—gradually comes to light is quite unexpected and creates a great 'gap moe' effect. The balance between the scenes with and without glasses is well-handled. While I wouldn't have minded if she kept them on the whole time, her bare face is actually quite cute, so the contrast created by taking them off worked well too. If you like the trope where a prim and proper woman is actually a pervert, this will definitely hit the spot.
