I decided to write a review for this because my overall impression slightly goes south from the majority. Four episodes in and: (1) I wasn't caring much for the characters, (2) I feel like I could even drop this drama. But of course I had to finish it, after all how could I just let go of such a wonderful ensemble cast. As for my weird reasoning, I fully realized why in the end. This isn't the type of drama that I'd marathon, more like an enjoyable filler that I can watch at leisure pace. I feel like it's too lengthy for its kind of story. It could have been kept at 16-episodes, or alternatively, it could have explored and given more scenes to the four men who were truly awesome when they're together, but apart, each of their storyline provides not much impact, and it was only thanks to these great actors who brought it to life in a splendid fashion. Besides the foursome buddies, the only couple with glowing chemistry is Yoon & Me Ahri. I attribute this to the underlying issues in their relationship which they had to overcome, and both actors came through for it. As to why I couldn't say the same for the main couple, it may be due to the overall direction and tone the drama took, which is just too much fluffiness. Should I even add, I couldn't connect much with the main couple and on the other hand, if Tae San & Yi Soo, who exudes more chemistry, had more developments then it might have improved my take on this drama. I understand that the goal was to showcase the male buddy system, different male personalities, how a man react to different situations in their life and relationships. It's great for what it's worth and I had too may LOL moments to not be positive about it plus to top it off, it gives you perfect pitch music that compliments everything from upbeat, funny, romantic, soulful, or sentimental. Because of these, I say it's worth re-watching just to recapture those laugh-out-loud moments. But, I'm not too thrilled of watching another 20-episodes of it again, so probably a lot will be skipped.
