So, I Can't Play H!

Ryousuke Kaga is a hopeless romantic who one day spots a girl with striking red eyes standing alone in the rain, ignored by everyone around her. Raised to respect women, he invites her to his place to dry off-only for her to suddenly stab him in the chest and vanish. But something doesn’t add up. Who is this strange girl, and why did she attack him? The truth might not be what it seems.
