Well the concepts regarding a single mother, her struggles, the mis-communication between parents & children, how the society treats children brought up by a single parent & how it affects the development of such children also the importance of communication between couples is well displayed.
Though some parts really disappointed me. The fl, she at times seemed like quite a reckless and irresponsible person but I won't judge her becoz everyone can't be perfect so that gave the story a realistic touch but while trying to make it realistic, the makers made her character too dramatic which stole the originality and realness. Personally the ml (child's father) wasn't to my liking either in the beginning atleast he seemed quite childish trying to deny his feelings by being too mean to the fl but their was slow character development on both sides.
And maybe because I have watched too many kdramas but the romantic plot seemed obvious to me from the 3rd or so ep & that was a big turn off. No just that but the sudden entry of all 4 guys also seemed a bit unreal and forced, after 8 or 9 EP , the drama lost all appeal to me & I dropped it so can't say much about the overall view.
