As much as I hate to say this, I'm really disappointed with this KBS BIG. It's a really cute/nice drama, yes. It started off really strong (which most kdramas are naturally good at imo), but as it progressed I lost more and more interest in it. For several reasons actually. One, they don't provide enough background for the main cast of the drama. Instead they provide way too many fillers with useless information and subplots such as the romance between Teacher Ae Kyung and Na Hyo Sang's little romance. Or even more unbelievably pointless, Teacher Kim Young Ok and Kang Kyung Joon's Uncle's relationship to Gil Da Ran's parents. While their comedic relief is undeniable the time used up on these people could be used to focus on more interesting and informative things like Kyung Joon and Mari's past. Or Yoon Jae's dad and Kyung Joon's mom. Or more importantly Yoon Jae himself, cause honestly after the guy got knocked the hell out we really lost the chance to see any sort of character development. What little flashbacks that were provided simply werent enough because they centered around Gil Da Ran and Yoon Jae as a couple, not him as an individual. Furthermore, how did Ma Ri and Kyung Joon become acquainted!? How'd she grow to be so in love (obsessed) with him? Besides a few flashback clips of him patting her on the head and her asking him to stop his mom from going to her dad, I really don't know much about this pairing's past. Also, another thing the writers could have shed a little more light on is the truth behind Yoon Jae and Lee Se Young's relationship. Was it really one sided? And if it was why the fuck would he take and KEEP the key she gave to him if he wasn't wavering in the least bit? Is he really as pure in thought and mind as the writers have tried to convince us after discovering Lee Se Young's lies. Speaking of the devil, Lee Se Young was a total waste of a potential character if you ask me. I mean really here you have two female antagonist, Seyoung and Mari, yet you give more screen time to the one who is mostly just an annoying fly on the wall with weak purpose. Other than being an manipulative and obnoxious little liar exactly what is she there for lmfao. It'd be something different if Kyung Joon actually had feelings for Mari which would create more tension and drama with a real love triangle. Or maybe a love square? I'm not sure? Can you really count Yoon Jae anymore since he's pretty much had no say in the matter for the last uh...15 episodes. But anyway, we can't really speak for Mari and Kyung Joon's past because like many other important things it's vague as fuck. As far as the casting goes, I think it's safe to say that Gong Yoo (((oppa))) saved this drama. As always his performance reeled me in like a fish. I swear when he cries angels grab the tissues and start dabbing away at their tears, lbr. Every emotion is so believable. LEE MIN JUNG. Love the girl i really do but i hate the character lmfao. She just seems so useless half the time? And only plays a game of tug of war with her feelings. Like really I can just picture her sitting on a park bench, plucking the petals off a sunflower and saying "I love him....I love him not...I love him...I love him not". Cause that's all her character did this entire time besides act like she older than Kyung Joon by 15 years and scold him restlessly even though he has more courage, patience, consistency, commitment, and sincerity in the tip of his finger than she possess in her entire fucking body. Honestly, she just proved to me that an age gap has little to do with maturity and readiness in terms of love. BUT I'M SORRY, i can't blame Lee Min Jung for having an "eh" role. I mean she didn't write it ykwim? Lmfao i really like her acting so I won't continue to complain. OK. BUT LASTLY. WHAT'S EVEN MORE UPSETTING IS HOW THIS DRAMA DRAGS ON AND ON AND ONNNNNNNNNNNNNNNNNNNNNNN AND ONNNNNNNNNNNNNNNNNNNNNNNNNNNNNN and ONNNNNNNNNNNNNN AND ONNNNNNNNN-....see what i did there. Yea. The writers spend most of the time making the main cast look like indecisive dumbasses instead of worrying about how to settle the "after come". Here's a timeline of what they do: exposition --> rising action --> CLIMAX? --> K nope rising action --> rising action --> CLIMAX NOW?..anybody? idk --> falling action? --> nope havent reached the climax i don't think --> a bunch of plot twists --> ok wtf are we even doing anymore --> finale resolution (lol hi) Lmfao. Kyung Joon hasn't returned to his own body and there's only 1 episode left to take care of that. Naturally, this will lead me to believe that everything will be jam packed into the finale. I'm praying that it won't be sloppy. I'm praying that it won't be a cop out ending in which they pull a "5 years later" type of thing. There's literally so many things to cover after they switch bodies back that it just leaves...to many doubts and little hopes for a clean end. If you ask me they could have spent less screen time on useless things like standing around crying while dramatic OST music plays in the background; or, knixed one of the supporting cast subplots on creating more time for the finale, in which all questions can be answered. All loose knots can be tied. Anyway, overall this drama just seems to be yet another predictable and shallow romance that can be used to pass time. It gets kudos for some of the exceptional pieces of eye candy though. But again, Gong Yoo was terrific and gives a heart trembling performance as always! So, if you're a huge fan of him you can give this drama a shot. (might edit after watching the last ep)
