Why does it feel like most of them are those dramas which didn't have romance tag.
Because I think more than 90% don't have romance tag, most of the Kdrama audience watch romance or zombie dramas and that's why non-kdrama watchers think kdramas are all about that.
The story was just okay, nothing extraordinary or unexpected. They should have considered that the characters are just school students they tried to portray them like adults but honestly I couldn't took them seriously and felt cringe at many places. They story lacked logic and consistency at many places. Seeing Park Gyu Young in it was really unexpected she have came really far after doing such minor roles.
Btw I agree with your last statement
Seeing Park Gyu Young in it was really unexpected she have came really far after doing such minor roles.
