This show tried to be many things at once, and failed at all of them.

I genuinely don't remember the last time a couple had this little chemistry between them, to the point where they don't even feel like potential love interests, they just sort of exist in the same space and time continuum.
In fact, the writers didn't even try all that much to get them together. For a show called "Touch", the main couple touched for the first time in EPISODE 13!!

All along you're aware that they're supposed to end up together somehow, but there's never anything to make you believe they will, and you kind of get tired of waiting.
I guess it's because the whole crew had to walk that thin line between romantic and creepy in order not to offend the wider audiences, which is what you get when you make stupid casting choices and pair the nation's favourite child actress with a 17 years older actor.

I'm sure the actors did their best, it's really kind of hard to pretend you're falling in love when you barely spend five minutes together in the course of 6 episodes.

With barely any romance in sight, the writers tried to play around with the themes of "less is more" in the beauty industry, or failing and getting back up to fight again, balancing the public and private life of celebrities, the harsh reality of kpop idols, domestic violence. Unfortunately, they never delved deeper nor fully committed to any of them, or at least not enough to make a point. The villain was kind of pitiful at times, until you remember he's a domestic abuser.

All in all, I was bored by the time I hit episode 7, and just kind of skipped my way through to the end.
