Both focus on very similar plots such as on a gangster and a “good guy” Trapped being a police officer and Kiseki being a Doctor, with enemies to lovers romance. They are both Taiwanese BL series and both have very similar themes and genres,

Both seem to focus on dark, messy and toxic relationships, with a lot of sex and not enough communication. They both have multiple couples and they all seem to sleep around with a lot of other people. They also both have the same writers with the plot of Only Friends not being as intense as Playboyy is supposed to be.

Both are mafia and/or gang based dramas with a similar gripping storyline. Both of these dramas are also BL series but one is Thai the other is Taiwanese.

The same writer, Sammon, wrote both of the novels for these upcoming series as well as quite a few others.

This series is the sequel to season 1 of My Engineer, both featuring the same cast members and couples.

The plot is pretty much exactly the same with both, except this is a Thai drama whereas My Hero is Taiwanese.

Both of these dramas and novels have been written by the same author, Dear Doctor has already been released and hopefully Cupid will soon follow.

This the main story Which links to the behind the scenes compilation released before the series began airing.
