prefacing this by saying that out of the 6 episodes, I properly watched 1-4, and 6.

Going into this drama knowing it was only 6 episodes, I wasn't expecting much, and I got exactly that. Though, I will say that it still managed to disappoint me.
The story started off rather promising if I'm being honest; the leads meet, and they create an app, so naturally I thought that app would end up being the focus of the show with the drama stemming off from that, but I was wrong.
maybe 2-3 episodes in, the whole app concept thing is practically left in the dust as it now focuses on some murder and other relationships that didn't nearly have enough backstory for it to justify their significant presence.
I won't go into much detail as to what else made me annoyed as that would spoil too much, but to summarise, 8/10 situations could have been solved using common sense and survival instincts.

Acting was alright, I've only seen 2 other T-Dramas prior so I don't have the right to judge much, but it did feel exaggerated at times.
minor elements such as cinematography and sound we're all good, J-Drama has something to learn from them haha.

TL;DR it's an alright show for killing time.
