Happiness is irony... title suggests something, drama itself never really follows the same path. Thinking about it, happiness is a vague concept... maybe like love. So not for everyone but the enjoyment, characters, the story provides might give happiness, not all-time but little glipms. It wasn't on my radar... honestly I jumped on the train without even reading synopsis or tags just for HHJ and PHS. And yes I was tricked as zombies were the last thing I was expecting from 'Happiness.'

It's not horror...at least I wasn't scared, there aren't many jumps scary moments as I found zombies a little funny (or it's just me who's weirdo). The story is pretty basic which doesn't give 'HELL! what happened?' moments, as most of the part I found pretty predictable even the biggest 'twist' I saw that coming miles away, so in the department of suspense, it's not that great. There are soooo many irritating, dumb characters (more than likable characters)... annoy you to death, will make you want to strangle, punch, kick their ass (well don't worry about this department our FL is master in it). Leads aren't 'perfect' so their decisions aren't always right, sometimes very reckless, they make a lot of mistakes. These are some shortcomings of the drama, if you have less endurance for any of these this isn't for you.

Happiness serves many very classic drama tropes, with done right! Lacking in some departments it gives more than what was promised manages to surprise even with cliches. With very less likable characters.. it makes you get emotionally invested in them, rooting for them, getting charmed by them.

The romance was the last thing I was expecting... honestly I'm no fan of forced romance in thrillers when it's just there for nothing other than a drag. But I'm completely sold for this couple... Gosh, the way they look at each other, their caring gaze, holding hands, hugs, I'm satisfied more than enough... I don't need big proposals, confessions, kisses, them just doing anything, talking with each other, fighting with zombies together being normal is satisfactory. And them being so natural... is the chemistry that I seek even in rom-coms.

As I said leads aren't perfect, they have their limitations/shortcomings. Sae Bom comes as very cool at the start, I loved her in prior episodes.. but then her characterizations aren't according to her profession as much I love strong female leads who can fight well... I get a little irritated by actions without consequences and the 'I think I'm doing always right' attitude. Even though I love her coolness and personality but, indeed, it's not true to what she should do as special forces are well-trained, very disciplined... so recklessness is the last thing you expect from 'special force officer' coz for god's sake they are trained for sensitive, life-endangering situations.

I loved her in action scenes, at a times she was more practical than Yi Hyun which was needed.. and yeah she's cool throughout. Yi Hyun is an almost ideal guy sweet, nice, sticking to morals, loving husband.. who can become a bad cop for his wife. He's so precious.. he's the lead guy where you won't get SLS (oops sorry I forgot it's a thriller, not romance). But he's being just being morally right wasn't always pleasant (that gave me 'Boy you don't have to be nice always' moments)... I loved when he gets angry and does things that viewers crave (satisfactory).

I'll admit I'm charmed by Han Tae Seok who's undoubtedly my fav character of the series, I have a soft corner for grey characters and he's total badass he's that person who doesn't give f*ck to right or wrong.. but still do things right, the only guy who can situation in the right way. He's interesting charming, with a good foundation of back story and with desperation.

might not be the greatest thriller... but it's satisfactory, entertaining, and keeps you on the edge of the seat even with the ordinary plot but interesting characters giving you happiness.
