Both dramas are set in the prosecution field, with a backstory that made the leads work in the law field. Both gave the same kind of feeling, with the main couple wanting to be together, but also too many things between them. Both have cute moments and intense moments!

Both dramas have the same writer and PD, and also star Lee Jong Suk who can be considered to have the same kind of character : both have been hurt in the past, and are trying to get over it in a way...

Both show have the same manager & stylist for the main character (Cheon Song Yi / Lee Min Ho) and they are so cute. Both shows also use LINE, since they are sponsored by it!
