Perhaps most of you are more observant than me but I immediately thought this was a webtoon that fell under the genre of romance, I think it may have been the description that led me astray as it sounded like a boy meets girl kinda thing...but no, it does not come under the romance genre. Yes, it has it as a subplot but it's not what the series is all about.
Because seriously there is soooo much emphasis on Da-jeong and Min-seong together and how they were never going to abandon each other and will spend everyday together, and that they're the happiest next to each other, all innocent hints that they want to spend the rest of their life together, yet suddenly it's hinted that the oppa considers Da-jeong as his girl friend or maybe just friend that is a girl?!? Yet then Da-jeong says that she's going to the amusement park with Min-seong, so is this a date or just taking the little brother to have fun? But then I realised that this is not a romance so Da-jeong and Min-seong just want to be best buddies that spend their entire life and every day in the future together...And Oppa is just someone who is joking about Da-jeong being his girlfriend to stop his friends nagging, oh btw I was fully expecting him to come out and say he was gay, and I'm sad(?) that he isn't XD Ahem, but anyways, am I the only one surprised? The Oppa seemed 100% side character and he never did anything much except comfort Da-jeong like how you'd comfort a child, he never seemed to /love/ Da-jeong as much as Min-seong. But really they're both great guys so I don't have any complaints, I'm just very surprised. And back to my point, this is why mindset matters, I read all the promises between them as a development to a romantic relationship, when actually they can be read as just simply the care between one human to another.
Now, onto the actual story... I think what drove the story, at least for me, is the effects of empathy. If you don't really empathize with anyone or relate things to yourself you are unlikely to enjoy the story as much or find it touching. For me, I was able to empathize with the family side of things, and those were the ones that made me cry the hardest... However, I do think that the story did have a bit too much crying in it, crying definitely works well on the occasion to emphasize something but if everything is being emphasized then nothing is... It felt like almost every chapter had some crying that I eventually became numb to it. It's a sweet slice-of-life that doesn't really have a goal/plot, it's just life problems.
Hmm, I don't really know how I feel about the story, I think the author did an amazing job and so the art is quite nice! It's got a unique plot idea and characters. So just looking at those things it's a great piece of work.. but I don't get the feeling that it's better than most pieces, above average certainly but not the best so in a way I feel that it's overrated...I'm not trying to deter you from reading but rather to just maybe keep your expectations realistic, it is a very nice story that you'll want to keep reading 🙂
