Review Detail of NotYourCat in Swimming Prodigy’s Return

I really love this novel but after the 8 years Time skip... my excitement and love disappear and got replaced by annoyance... okay let's start this with what I love about this novel: 1. I love the MC childhood pary character, he is kinda narcistic, but adorable at the same time... the jokes are funny and love the interactions with other characters 2. the concept, altho there is already many of this 2nd chance concept, I always love it... and morever this is harem... 3. overall I liked the childhood arc, altho there is sometime that made me wonder wtf did I read, or some bad decisions... and here is what I didn't like about the story: 1. the system... I think it is better if there is no system in this story... fiest of all the world in this story is based on our reality, so system is really overkill, so to balance it, the system and MC must get nerfed... and this nerf made the MC looks really useless... it's all good at the childhood part, because the system do it's job properly, the MC is the best in his age range event the one that 5-6 years old than him... well he has the system afterall... so it's normal... but after the 8 years time skip... things turned in to shit: he lose in the race with his peers, sudden Tax for the shitty stupid fvkin unfunny system, and we know that many other people under 16 has stats better then MC , like wtf... after 8 years MC only has avarage human stats, like wtf? if you said that his stats that almost in 80, it's because of the equipment from the system! and his peers doesn't have that kind of system... so his normal stat is -30 or even less than his peers on olympic under 16... and this is really annoying and made me as the reader uncomfortable... if you want him to really work his ass then you better remove the system... because with the system he looks like useless lass that even he is trained hard, his normal stat is only avarage person... and it's frustated the reader 2. what I hate after 8 years time skip, the character lost their charm, even the MC... he is just become regular popular guy with no uniqueness.... 3. 8 years!! did he didn't do anything for his future? he know his father will die because of overwork, why didn't he gave his parent an idea or two about money, like stock market investment, or business idea that will blow up becaue of lifestyle change... it's 8 years afterall... damn it... even Xiaomi becoming one of leading smartphone industry in just 10 years, and they started it from zero... aaarrrggghhhhhhhhhh it's frustated me more because I love what you do in the childhood part if I can give you some suggestions 1. Imo, story is about conveying feeling... you should think what kind of feeling you want to convey in this story? what overall feeling you want to convey from start of this story to the end, what kind of feeling you want to give in each arc, what kind of feeling you want to convey on each chapter, event the feeling you want to convey on each paragraph, sentences, and word, you need to think of it... 2. think about who is your target audiences, or who is going to read your story... from your tag you can already now that this story reader is people who likes wishfullfillment (2nd chance), people who likes harem, romance, and sport, you already targeting the audiences with your tag... so you should think the development your story... not develop story base on your target audiences... you can develop the story however you want, but IMO, just don't develop it into something that will make you lost your audience, a.k.a don't write what your audience didn't like... something like nerfing is what usually people on Wishfillfullment categorybhate, or NTR is what usually hated for people who like harem genre... that's all from me... I hope thos story development wipl be better than just "ordinary" kind of development because with 2nd chances and system, if the development still ordinary, I know that the MC is worse than his last live...
