'The Interest of Love' is a well paced, well written drama and the plot is easy to follow. The characters feel real, so maybe that's why some viewers have a problem with watching this drama. Like none of them are unrealistic, and not the candy typical far from reality that Kdramas like. Everyone in the cast is doing a fabulous job portraying their roles. All the emotions, confusion and acceptance in each episode, I love it. This will definitely make your blood boil, as well as make you frustrated. Like all of this workplace bullying, overt sexual harassment, and gossiping coworkers just screams toxic environment. Moon Ga-young, Yoo Yeon-seok, Keum Sae-rok, and Jung Ga-ram are all doing amazing. Fingers are crossed that this ends happily and we don't get yet another sad ending that screenwriters like to do nowadays. For now though everything is going smoothly and I'm genuinely enjoying the drama.

(EDITED)
So I finished the drama, and all I have to say is that give it some time before you decided to drop it or give it a bad rating. The ending wrapped up nicely for me and made sense.
