This started as such a fun drama, it felt like watching an anime in real life, with the silliness of his masochistic tendencies. I liked her strength, and they had okay chemistry, nothing amazing but there were at least a little? Episode after episode I kept waiting for an advancement in their relationship but got nothing. He turned into a complete and utter, creepy stalker and she sort of floated, like instead of falling in love she just accepted the harassment. It's a shame, what could've been a funny, quirky show about a secret sadist and a masochist turned into a show about, it's okay to stalk someone if we categorise it as romance.
