Okay, first we see both main girl & main boy as 17-year olds. Despite the infamous common practice, they were not portrayed by 30 year old actors. Yoon Chan Young and Park Si Eun were both really 17. Actually, they were both so talented and likeable that at first I worried I will not be able to like the grown-up versions as much, in compare.

As for the story: Main girl got robbed of 13 years of her life. Suddenly waking up in a body of a 30-year old, her mind was still 17, without the time to allow her grow up and evolve, develop her personality, adjust to her body change... Or completing her education and gaining working skill, to mention the practical. First thing I thought was that along with physiotherapy she'll require a psychologist, and some support. But her family was nowhere to be seen. As for main guy, at the tender age of 17, when he liked a certain pretty girl and first tried to approach her, she obeyed his advice to get off on a different bus stop, which (in his mind) caused her to die in following accident. After this, he decided to live alone in woods. Okay, maybe not so extreme. Basically, he keeps a long beard and a dog:) That way he maintains his distance from females, while pouring all emotional attachment onto the small creature.

Shin Hye Sun had interesting acting task, here. Her 30 year old face was now supposed to wear expressions a 17 would make. Same with her manner of speech, and general behavior...

First episodes, the girl struggles with physio for a while and with seeing her own face and hearing her own voice for long. We don't see her getting any visits, the facility staff keeps avoiding her questions. The guy maintains slightly antisocial behavior. I had to smile. I personally could relate, it's the same whenever I attempt to act like that. In our society, you practically cannot get through 1 day, if you'd just purely attempt to not interact with any people around you. You unavoidably end up perceived as rude, mean even. Nobody would ever understand you'd like 1 single day of social "cleanse" from all the communicating. You really need to lock yourself alone for that:) Main girl and guy mirror each other when she seeks after company while he tries to avoid it.

Episode 2 ends up in crazy confusing situation where I was equally confused while I was the audience, lol. But actually, it was kind of tragic... Main girl was still recognized by her old dog, else, her house got new owner and her family members were gone. She was told to go to the police. Yeah, I indeed thought the story of a young girl having woken up in a strange adult body, in a strange world where she had no one, was not very cheerful. I would understand if she started to cry. The scene where even police refuses to help her is especially weird. Apparently before the accident, she was not legal age enough to receive ID card, but her appearance was older now, so the police just refused to help her. I was confused, why nobody in the facility having her medical record didn't provide her assistance with such matters, or why did all of her family members disappeared. But, perhaps the writer needed to create situation where she'd have only the main guy to provide help to her.

Main guy looses his long hair episode 3, unfortunatelly he gets that weird helmet-shaped haircut they sometimes do to guys in Korea so I actually did not find it that much of an improvement. Who needed his hair shorter was the main girl (well, woman). Anyways. The following episodes, she continues staying in main guy's house, who grudgingly allowed it for 1 month. I couldn't help but thinking she'd be better off had he not. She was a grown-up looking woman acting like a 17-year old, which was not always looked kindly upon. She kept going around for job interviews with completely empty resume, as she haven't even finished high school. She was not able to play violin with her new hands. She actually needed lot of help, unfortunatelly the writer's plot made it so that she left the only place where she could be found to receive it. It was frustrating to watch. The main guy needed to learn about her identity to start treating her better and also to start healing. But that was obviously also something the writer wanted to happen way later...

I kept watching, because I agreed it was more important for the girl to meet her right guy, after all:) She was stuck in being seventeen, he was also stuck in the past, so that way they suited each other. It was right for them to meet (again). They started to develop a connection, to realize and address important things, just everything but him realizing who she was. That was always conveniently swept under a rug. Apart from these obvious flaws, soon it all comes together, even with such characters like too noisy friends or too weird a housekeeper, it somehow clicks and the drama works: it's enjoyable, funny and heartwarming.

ML knows about FL's identity since epi 14/16. Better late than later. By that point, FL's got 3 suitors (counting ML in). There is still yet the Mystery about her family & about the housekeeper, and mysterious man in a baseball cap. Despite all these corny elements, I liked the humble quality the main girl had. She knew grattitude, not just attitude, like all them leading ladies:) It's actually easier for people of this kind to find happiness, and I liked the drama did mention that. Romance is very satisfying, the romantic conclusion comes earlier than the final and really is quite romantic. Then there's more heavy drama about the family stuff. I didn't enjoy watching main girl going through even more pain, but at least by then she had her guy by her side. Luckilly, some more cute moments follow.

And questions about their future. But the girl was younger than her age, so I didn't see why she should not study if she wanted to. And the guy was used to being uprooted. The way I saw it, nothing prevented the guys from getting married and going to Germany together for one or two years, even with the dog:) Then they could return to their korean home and she could complete her degree. I didn't see a problem, no matter how many years it all should take (so what if you get your degree at 38 or 40 years old? if it's the craft you long to practice till you're whitehaired:) Life is long. No need to rush your journey WHEN you already have the right person to walk hand in hand with. The writer tried a to make bit of final drama out of it and we had a couple of separations and reunions of the characters, so the ending was a bit zigzagging but the emphasis was on friendship and love.

Overall, it was a good melodrama.
