First of all, i am writing this review to thank the director and screenwriter of this drama for the way they have folded the season 2 of it, such unpleased watcher.
Second, the main story(5.5 rating) is disappointing and messed up for a love triangle to end this way, Kim jojo dumping sun-oh for not clear reason and chose hye-young while she doesn't believe in her feeling and sincerity and because of her terrible scar of the past that shadowed her present life. Her immature acts lead her to hurt the feeling of others and i think she deserves a beating just to wake up from the dark hole that surround her and influence negatively the persons she love. My anger got alleviated a bit by apologizing to sun-oh for her misdeeds but still she needs to give a reason!!!
Third, i gave a 7 overall rating because of the side stories that were interesting, geul mi hardworking to enter that badge club and her discovery that the developer is choi suk duk the one who rang her love alarm and she rejected him is quite epic and funny, that suk-duk is a thing but this 2.0 function created a disturb and caused some suicide crimes so he wanted to remove it after the person called as his brother and the fake developer of love alarm was keen to activate it. Geul mi believing in herself despite her continuing fails make her suscced in the end she even forsaken her online shopping to enter the club, i liked her character.
Fourth, the acting and ost were amazing and well played whether by the leads or the supporters that why i gave a rate of 8.0. The ost called tearliner is quite impressing.
In general, i don't recommend to rewatch this drama but those who will to watch give it a try even if i spoiled everything her
