I have not much to say - and I’m on ep7 - but I feel the casting&director missed a trick here!

The story is simple, the writer kept the side stories to a minimum. Which is okay if the main story held a bit more weigh - what is killing it for me is the main male character. It’s infuriating that they left KYK to play this two dimensional persona, with no charisma, relatability and non expression ! I just wished I can go and slap him to start acting- he is playing someone depressed and lonely - and I know, those people are hardly two dimensional; character with two impressions
She is a bit better, but not much - I’ve seen her chapter before from her.
The rest of the cast is is ok - the “lower” you go on the pecking order the better then actors actually!
But why no one told him that being tall and handsome is not enough to play a complex character?! Why?!
