I'm writing this rec for both season one and two because I watched them together like a regular drama (why netflix has to cut things like that /: )

Overall I liked the show, it was mostly light and fluffy, ideal if you don't feel like thinking too much, also it was very pleasing aesthetically, really cinematic!
I was mesmerized with that Seul scenery on the rooftop *_*
The theme of this drama is basically the transition from friends to lovers with teens so it implies a character growth as well (more or less)
Tae Oh was my favorite character even tho in the beginning I felt he was too childish, but I think that flaw blends well with the role and his journey. He was cute and really caring for his friends and very very supportive, I really liked the characterization and the actor really played him well imo.
Also Song Yi was pretty cute, she looked a bit drained (?) but overall she wasn't annoying or dense.
As well the friendship relationship between all the characters was pure and cute.
Ga Rin and Choi Hoon were more comic relief than else, their story lacked in screen time and complexity. Cute, but meh.
Do Hyun was the "problematic" one but I liked the fact that there was not just black or white. Yes, he wasn't there for her when she needed him the most, but he had his own issues and they were as serious as hers. Sometimes in life happens that it's just the wrong moment, the wrong place. It made me sad not being able to blame a villain (?), it's just how life goes sometimes.
That said I didn't like Do Hyun from the start because I knew he was going to be messy: and not the money issues itself, Song Yi too was penniless, but the fact he seen himself inferior to Tae-O especially, the fact he thought a man had to solve his issues by himself instead of relying on his girlfriend. He was ashamed of his status and he thought he wasn't worthy because "he couldn't protect her", while a genuine relationship is made of reciprocation and support from both sides. He was stuck with this ideal of the brave knight so he couldn't see that Song Yi didn't need a perfect guy, just someone whom she can rely on. In the end he clearly understood his mistakes and that are some brownie points to him.
I gave only 5.5 on the story because it was pretty much it, mostly is about Tae Oh trying to replace Song Yi in his heart with that stupid gal and Do Hyun being insecure about himself.
Though I loved the spontaneity of Tae Oh's confession at the pub, without annoying slo-mo or dramatic stares, candles and all that heart shaped and pink stuff they usually decor for their grand confession, it felt sudden? like there was almost no progress for almost the whole second part, because they focused more on the guys finding back the moms (gonna talk about it later. - note that the period here indicates angst) so it's like a time skip but in fact it happen in the same moment. There was a more noticeable transition from friend to love interest in his part, while she jumped from a boyfriend to another. Yes, they both had some feeling from each other but Idk it felt weird and unexpected...maybe it's exactly because I was expecting candles and hearts xD

But let's talk about the parents: we have two moms abandoning their children, a dad telling his son to quit school because of debts, a stepmom saying "I don't like him" referred to her stepson, one that beaten up his son with a golf club because he wanted to be a musical actor and subsequently trying to parachute him into a play with bribes...wtf! Ga Rin's mom and Tae Oh's dad were supposed to be the scary and bitchy ones but they were pretty good compared to these...at least they cared for their kids even in a weird and distorted way.
Both Tae Oh and Song Yi mothers neglected and abandoned their kids in a way that doesn't even make sense, especially Song Yi's mom. I thought she had a serious reason to stay away...idk anything - usually is illness - or maybe she was a criminal (?) idk ...but she just met a guy and neglected totally her daughter while strolling in the night marked with her sweetheart??? I mean she didn't even thought about giving her some money or else to help??? she was on the freaking streets!!! What if Tae Oh wasn't there? What if he was living with his family??
I went through a similar path and the way they painted the mom as sorrowful is making me puke. there's no freaking excuse for abandoning your child! Even if she's not a minor.
Same thing about Tae Oh's mom...even tho she was forced by her gangster brothers (?) to leave...couldn't they just transfer somewhere else together?! And after all that time why keep going on with the lie??? Absurd.
Another character I despised was Se Hyun, and not because she was confident...she was pretty much flat. Who's she? what did she do when she wasn't with Tae Oh? why was she so bitchy and demanding? What were her struggles? She just treated Tae Oh like a carpet most of the time, playing with his feelings because she knew she was pretty, I call that lazy writing, sorry.

I suggest to give it a try if you search something unpretentious, just to fill in or when you're in a slump (lately I'm always in a slump. I don't know if it's me being more selective or dramaland becoming more boring and uninteresting ç___ç)
