Bad Buddy is without a doubt one of the best BL I have ever watched. The chemistry between the characters, their acting, the story, the setting is just perfect.
The acting and character development of Ohm and Nanon is just flawless.
One thing I would like to suggest to people who are yet to watch this series is not to watch the teasers of the next episodes before watching them, especially the final episode.
I was able to predict the final episode just by looking at the teaser and was a bit disappointed when I watched it as I thought my prediction is just a part of the actual story.
I recently read the novel and found out that the story is quite different from the series, I find that the story is better in the series whereas the ending is better in the novel.
I think the novel's version can be presented as season 2, the timeline being before the final episode.
