The story is about a beta, slightly broken MC who gets caught up in a plot to torture a girl that he has a crush on. Other girls appear and quickly fall in love with him because of how sensitive he is to their wants and needs. Some of the girls are caught up in issues related to gangs, others in issues related to high society, but all of them have a connection to the brothel he is now a part of. He bounces from story to story, promising to take responsibility for the girls he has s*x with, while they do the heavy lifting in regards to making things happen with the plot. The problem is the bad writing. Too many issues are solved by the character just being "such a perfect match"for the girls. Every girl has some issue that can only be resolved by somebody as considerate as the MC. So they are more than happy to share him with the rest of the harem (8 that he has slept with, plus 3 that intend to sleep with him soon). There is mention of deeper plots going on, and it is interesting when they finish playing out, but they don't make any real sense because the MC, and by extension the reader, never get to see any details. We are just presented with an impressive end result and told that the plan was very complex and impressive. But it never is. For instance, one of the story arcs involves a battle at a hotel. It starts with a bunch of people attacking (the battles in this are awful) and ends with a powerful wealthy man weeding out traitors. We are told that it was all very impressive and intricate, but a bunch of high school kids manage to wander about as they please, and the MC, who wasn't even supposed to be there, winds up having to kill somebody to clean up loose ends. Other "intricate" plots are the same.
one of the harem members can use qi to fight. She is basically a jedi. She can use qi to sense people's thoughts/feelings, and can cause them to stumble with a wave of her hand once she has grasped their qi. Also, the hotel battle is supposed to be some high level battle between some of the most dangerous guns-for-hire in Japan and some foreign terrorists. The battle is indescribable nonsense.
At one point, somebody notices that the MC doesn't value his life and is willing to accept death. The harem members are very sad to hear this and spend the entire chapter convincing him that he is no longer alone and had something to live for now (family). The MC realizes that they are right, and vows to them and to himself that he will treasure his life. 30 chapters later the process repeats itself, and all of the involved characters act like they are dealing with this for the first time. Even the MC thinks something along the lines of "I didn't notice it before, but I'm not attaching any importance to my life. That's going to change though, because now I have a family!" Then another 30 chapters later the exact same thing happens.
I eventually stopped reading when the author completely forgot about the prince's aide. After multiple chapters of nothing important happening, the MC starts to hang out with the Prince who is his class mate. Not to be confused with the young prince who comes to view him as a brother in the early chapters (another example of why his fear of some weird plot failure loses any credible threat). However, after several chapters of the two hanging out, I noticed that the prince's aide was nowhere to be seen, and no explanation was given. This is the aide who had shadowed the prince everywhere for the entire story until that point, only leaving the prince's side to hang out with the MC, whom he had developed an interest in. The arc immediately preceding this arc had heavily developed the character, but then he was nowhere to be seen in this arc, which would require actual explanation for his absence. A lot of the story was like this. The primary love interest was never developed at a pace that could be considered acceptable; a secondary love interest (the MC of the game he reincarnated into) was dealt with in a weird way where she seemed to be interested in the MC, then was interested in a random side character, then was doing some other thing; and various things the MC did would just be sort of left kind of completed (starting new stuff in his territory then leaving all the development to his father, a princess with odd luck who always seems like she's going to meet him but doesn't, various incidents at school that seem interesting but never really go anywhere, etc.). Basically a story with a lot of wasted potential.
starts focusing on making sure people don't feel unhappy, because negative emotions create monsters.
