The whole time I was thinking that the movie should be about the father and the baby, but it was actually about who is the BABY BESIDE ME let me find her mother and ask about the father of the baby.

Not to say bad but I was highly disappointed by the movie. since I watched it already, it has one good thing which is the fabulous acting of Lee Yi Kyung, he just aced the role of a young father. He reminds me of Jung Hae In from One Spring Night and Jang Geun Suk from Baby And I. all these have one thing in common: a young father who thinks knows everything around him but is betrayed and left alone. While the latter two have a bit of subtle comic elements which made them light, Baby beside me deals with the harsh reality of making an immature adult into a self-discovered true adult.

Do-il had got all the suffering that life could offer when he is about to have happy married life with a wife and a kid, having the Job as a gym trainer, but it comes crashing down where he had to question the choices he had made in the past. It seems as if he knew nothing about his girlfriend's past including his mother's sickness. But this big blow subsides and he gets used to life and starts earning pennies to survive from whatever he could do.
The ending is quite surprising, as I expected it to be the answer but instead, it served the emotions of belief and forgiveness.

The subtle colours in the scene were perfect depicting the mood of the movie with Do-il suffering. Music was similarly fine and skillful maintains the tone and atmosphere.

it is a good movie with a powerful performance by Lee Yi Kyung but I won't rewatch it as it loses points in terms of story.
