I feel like the entire premise of him being a seducer is thrown out the window after two episodes.The friendship between the three becomes a gimmick more than an actual friendship later on.The romance between tae hee and si hyun was great to watch until they started breaking it off and getting back together at every obstacle they face. Every time it becomes hard, break up.Opening up and talking about your problems is real hard, feeling guilty towards your SO is an instant relationship killer. the writing is bad that's all. you have to stretch it out to 16 episodes but you don't have any story elements to work with. it becomes a mess of plot reveals that have been hidden for way too long, and misunderstandings, that said it doesn't excuse the plot since many other dramas have done well without it too. I feel like once the relationship has been achieved, you have to put the couple in different situations to the point of breaking up but they overcome it and comeback stronger than before, not break them apart every time and get them back after a time skip.
their friendship was hard to watch, soo ji was basically used to steer the plot, oh wait lets give her a relationship with se joo to make it more appealing.
the entire story is just basic kdrama tropes we all love so much, it was a fun watch while it lasted. joy was great in this kdrama, I have a problem with kdrama leads who look stoned all the time but si hyun had some great scenes but if you are looking for innovative storytelling, interesting character development. this ain't for you.
