Its actually impossible for a normal person to treat this as a normal romance comedy. Why? 2 reason on why this is so wrong.
1. The hero is basically an obsessive stalking kidnapper type.
2. The Demon Queen is basically suffering from Stockholm Syndrome.
3. This premise, if not considered a "comedy" is wrong on soooo many levels. Its like saying racism or rape is okay as long as its a joke. Not in the 21st century.
4. Its not really that funny. The hero comes off as incredibly annoying, and that each chapter I feel bad for the Demon Queen because she is basically being confined without consent, and the are saying its okay because he loves her. If you have read Mirai Nikki, then you know that doesn't work. This is the exact same thing.
But yeah. Its not really that funny either, so I can't really give it a pass on trying to portray someone's horrific circumstances as comedy.
The Demon King's Daughter Is Way Too Easy is almost the same type of romance, except its done better and funnier.
But if you like this and are fine with it like revenge rape series, harem sex parties, loli-pokemon series, then I guess you can ignore the premise of this series and find it entertaining.
