If you like watching two attractive people constantly bickering, and teasing each other, while being in total denial about the fact that they are falling in love, this is for you! If you are looking for a complicated plot that's unpredictable, realistic, and original, you've ended up in the wrong place. This is 100% pure cheesy rom com, and I ate it up! Rain is incredibly cute, and often shirtless, as the stubbornly childish Lee Young Jae. Song Hye Kyo is endearing as the unbelievably naive, and ditzy Han Ji Eun. The first two episodes are filled with totally unrealistic, but pretty amusing, situations that end in a false marriage, and the two leads having to learn to live together. Full House paves the way for many future K-drama clichés, since they work so well in this one (like "Personal Taste", which Is my first K-drama love). Everything is basically straight from the K-drama RomCom handbook (unrealistic chance encounters, unbelievable coincidence, nursing people back to health, rich vs broke, OCD vs slob, frustrating misunderstandings, running through airports, Hallyu star scandals, love squares... ) and most of it works. The cast is what makes it work so well, and kept the sometimes repetitive moments entertaining. I also think the leads, & their romantic rivals, do show some depth. I loved to hate Han Eun Jung as needy Kang Hye Won. Kim Sung Soo as Yoo Min Hyuk was a little one-note throughout, but still made for an appealing 2nd lead (but those eyebrows???!!!). I really disliked Han Ji Eun's two "best friends" who's audacity was hard to believe, and watch, but I think that is the fault of the writers, not the actors. One of my favorite supporting characters was the grandmother, and I thought the family scenes were really cute. This drama could have easily been cut a little shorter. They made sure to drag out the banter & bickering to the last possible moments, because they know it's what people like to see from the leads. It's clear, during the last two episodes, that they ran out of story, and that they had to rely heavily on flashbacks to fill the time. The leads do a good job of keeping the chemistry going, so the final moments still have some entertainment value, and I did really like the final moments with the 4 main characters. If you're in the mood for a love story without any frills, give this one a try. I have already rewatched it, and it doesn't lose it's charm with the 2nd viewing, nor does it feel too dated (just the phones). The soundtrack is also incredibly catchy. For better or worse, I found myself humming the songs to myself. The key to liking this drama is knowing what to expect. It's a lighthearted innocent romance that's fun to watch if you're in a romcom mood. It's still converting people into drama-addicts for a reason. Aja, Aja, Fighting!
