67 of last 108 chapters are all replaced entirely with some other novel's chapters repeating the same several chapters from those novels so you're completely lost when it comes back to the actual story, list of replaced chapters: 1264, 1267-1269, 1273-1275, 1279-1284, 1288-1311, 1318-1323, 1327-1332, 1336-1344, 1348-1353, 1366-1367, 1370. Will occasionally have missing parts thoughout, this becomes especially noticable when approaching ch 800 when entire sections are missing and come across chapters that are only roughly 20-25% the size of a normal chapter. I could confidently say there is AT LEAST a dozen chapters worth of material missing. For example chapters: 882, 883, 885, 914, 915, 925, 928, 929, 934, 935, 940, 959, 970, 975, 999, 1011, 1033, 1034, 1036, 1050, 1054, 1059, 1061, 1067, 1084 can be easily seen to have most of it missing. Several of these are during intense scene's that just get skipped over, some include challenge's from the system so you never know what needs to be done or the reward. The novel is about having a system and this system's challenges all revolve around women around him and mostly progressing relationships yet he stays "pure" until around 340's and the responses to women make it sound like the mc has a mentality of a middle schooler which seems appropriate considering the translation keeps saying he's in middle school even though preparing for college entrance strangely thoughout the entire senior year with a monthly mock exam for position within school. Situations are just non-sensical or hypocritical where he'll try to do the same exact thing he feels like he has to catch someone doing to get justice for because it's just not right. Some scene's are thrown in to try explaining something like even though he's in school on mornings, and weekends it's already following his actions, somehow he's in 2 places at once having been meeting someone frequently during morning practice just to give the backstory of knowing this person.

Premise is alright but the MC is like a frightened teenager beta thats completely whipped by girls. It keeps trying to be funny but falls flat, he'll bring weak extras into a combat area, system points just sit there without a show of saving for something. So many faults that it's difficult to list them all.
