The only one I've seen amongst all you listed is 'King the Land' and it was lovely. It's no doubt that the story line is the same as others with the CEO, being head over heels in love with his worker. Lol. I still enjoy it regardless especially when it has to do with two beautiful characters.
As for 'Queen of Tears', I've added it to my watch list for when I'm on holiday. The last one seems pretty interesting though. Will check it out. Thanks for sharing.
Le daré una oportunidad a King Land, últimamente he visto muy buenas Reseñas.
