Review Detail of Rahmani_Ayu in Small upgrade system

like jisoo meme: it is good but not that good.. for me everythinh good but what i dont like is, this story kind of fast but to slow too.. what make it slow is it was like we reading mc journal.. what time he wake up, how long he's training, how many times he taking a bath.. for grammar, well sometime i have a headache reading this.. but i dont care because my english isnt good too.. lol
