Sweet Sweet (2021)

The storyline is different, there are more "fantasy" elements in Love O'Clock. BUT its similar vibes:
- they are both super fluffy
- FL is bubbly and more flexible/"lazy" and creative (and talented), while ML is very particular and talented
- there is co-habitation in LO and they are neighbors in SS
- they develop feelings quite fast but they become official quite slow
- something else brings them together (LO is a clock, SS is ice cream); the FL has something the ML wants

Story line more or less same
-ML is suffering from insomnia but able to sleep with help FL
-In both drama FL and ML neighbours
-Similar vibes
-ML and FL develop feelings mutually in a slow pace.

If Sweet Sweet is early twenties version then My Neighbour can't sleep is late teen version.

the similarity between there dramas are
the ml/fl are suffering and the fl/ml are the only ones that can help

both these dramas include a ML with a psychological conditions in SS the ML ends up sampling her ice cream – and discovers that it remarkably relieves his aphasia symptoms, albeit on a temporary basis. Just a spoonful of the homemade ice cream allows him to communicate totally unimpaired
whereas in SIMU the FL falls for the ML's deserts

I think this drama will be so hit just because of Zhao yi qin... he is so handsome and good looking. Every modern drama will be a hit if he will be the lead hero.
Everyone shoukd watch his drama MY GIRL and MY YOUTH. HIS MOLE IS SUPER SEXY. He is one of the most handsome chinese actor

He is so hot. He is the eye candy in every drama. He shoukd do more and more main leads. His new drama my girl is very famous now.
