1) Pak Seo Joon is in both.
2) Pak Seo Joon's character's personality is a bit like Siwon's personality in She Was Pretty (hilarious and a childish..in a good way!)
3) In both of the stories, the main characters are working in a office for a magazine & there is a boss/employee romantic relationship going on.
4) Both are fast-paced and make you laugh a lot!

In short, if you like SWP, I think you'd like WR :)!
