What is the fine-grained topic of the following text: Our fav youtube show before we got netflix was 爱情保卫战, though it is slowly being replaced by another favorite 一转成双, which I was reassured by Mr Bear that would deliver violence on top of the volatile relationships ( I had to watch like 20+ blurry episodes before someone finally got slapped). Only return the topic.
