There are just three downsides to this drama that could probably turn off some people. Otherwise, it was a pretty entertaining drama.

One, there's lots of screaming from the ML. Like a ridiculous amount and even in scenes where it is not necessary. He is a character written specifically to scream in every scene. And also to smack his lips and play with his tongue every time he's onscreen.

Two, there are story arcs that are quickly abandoned and forgotten. There's one where the restaurant is struggling to make ends meet with the kitchen in disarray, but after a few episodes despite kitchen continuing to be a mess the problem goes away with no closure. There's also an arc about the chef banning pickles and some other items in the menu from the restaurant but after a few episodes, he's okay reinstating the items to the menu with no explanation.

Three, the FL is really charming but is one big masochist taking all the verbal abuse from the chef and falls in love with him despite being treated like crap.
