Review Detail of Samelies in Second chance?! [Dropped! For now!]

First off grammar sucks and does not get better. Second the MC is made out to know the world but many times completely skips over key points. Third the MC is worthless, he is so weak willed and quick to mental breaks that make no sense that I got whiplash. Fourth the characters of DanMachi are portrayed with VERY different personalities to the OG works, like Ryuu cries after threatening to murder a kid...... I..... I don't even know where to start..... Fifth is that the MC tells like ALL his secrets to like everyone the day of or after meeting them for the first time.....
