(this review could be biased by the fact that I actually imagined myself having children with that Man)
let's start by the most important factor that made this drama that good, THE ACTING, Woo Do Whan was too good I was feeling all the distress he was feeling, he is such a great actor that many times is judged only by his (EXTREMELY) good looks but he was outstanding and he should get more reconignotion for that, also the chemistry between the main couple was such a different vibe from the one they usually deliver in K-dramas, it was like they actually were a couple that were in love but then broke up but still love each other, and it's shown in the way they are not embarrassed and they feel very comfortable with each other.
The plot was cool but very tragic and made me stare at the wall thinking about how I am wasting my life not making the right choices.
The music choice was unexpected in the most positive way, California dreaming is stuck in my head rent free.
I would recommend this drama 100000/10 cause it's also the reason I am now starting watching dramas again. <3
