I am pleasantly surprised at how thoroughly I enjoy this drama. This was a perfect cute, fluffy, and light-hearted drama. I was literally smiling and giddy for almost the entire drama. I even LOLed at some scenes. I previously watched Touch Your Heart which was kind of a struggle to get through and surprisingly, a few of the side characters of Touch Your Heart showed up in My Roommate is Gumiho. But unlike Touch Your Heart, MRIG does the light-hearted, fluffy drama theme so much better.
I loved the relationship between the two main leads but I especially liked the female lead. I absolutely adored Hae-sun in this drama though. Initially. I thought she was going to turn into a villain later on because secretly she was in love with Sir the entire time. But I'm so glad that wasn't the case. I loved her love-hate friendship that she had with Sir. They both aren't good at being honest and nice to each other so they expressed their love for each other through their banter. I also loved that she was completely willing to protect and support Lee Dan every time she needed it. I'm glad she was paired with Jae-jin, I didn't expect it but they're a sweet couple to watch. I would've loved to see the Mountain Spirit in the last episode while they were tying things up but it's okay. I still loved the wrapping up of the final episode.
I really did feel bad for Seon-woo though. Even though he was a mega-jerk at the start of the drama, I still found myself liking him and if Sir wasn't in the picture, I really wouldn't have minded if Seon-woo and Lee-Dan got together. Of course, that would turn this drama into an entirely different drama.
Anyways, I'm really glad I decided to give this drama a try instead of skipping it. Maybe one day, I'll come back and re-watch it just for the laughs.
