The MC and his teacher that time are just total scums, lowest of the lowest. (Even with all the background later on trying to make me sympathize with them.

I get it, MC should get the harem. But come on, the girls are addicted to him just because they c*m first before him. It that even a substance for a lot of characters?

1. Character Development: most characters have quite a decent character development. A lot of them are quite colorful and multi-dimensional. Even if the story is repetitive sometimes, the characters are good enough that it keeps you going.
2. Setting: I won't say that it's realistic, but it's not completely unrealistic either. It's a vibrant unrealistic setting based on reality. Nobility, underground society, secret Qi arts, etc. Powers that can ignore laws and control a country to some degree make the story thrilling as the MC obtains them one by one.
3. Psychology: the psychology of each character is analyzed thoroughly in a way that gets down to the root of the problem. Various traumas and ideals, you'll be able to relate to them and realize a lot of things in real life. It's a rare experience to gain life lessons from an ero novel.
4. s*x Scenes: this novel sticks to the orthodox s*x without going too overboard nor soft. The MC always goes for cr**mpies with the feeling of making the girls pregnant. No machines/tortures involved, which I prefer. The MC loves everyone he has s*x with and treats them dearly.

1. Main Character: quite debatable. But he's extremely passive and selfless like a robot. He won't move unless people around him tell him to. He's quite a unique character, but not that unique at the same time. I won't say much, but I can tell you that you'll be disappointed if you expect too much. He's not OP, but his women are.
2. Slow pace: this is one of the most slow-paced novels out there; one day's worth of story goes on for dozens of chapters. 600 chapters worth of story only spans around 2 weeks of the story. Nothing much will happen in just 5 or 10 chapters as there's quite a bit of winding up before shits go down. Don't expect time-skips where the MC comes back with huge growths (although there's a minor one). Everything is extremely gradual. This can be a pro depending on your taste.
3. Excessive trivia and history: trivia and history can be good when used well, but the author ab*ses them too much that it gets boring a lot of times. One paragraph might suffice for the purpose of the story, but the author often dumps an entire chapter worth of them.
4. The loli's: the story didn't start off with many loli's at all, but after a certain point in the plot, loli's started flooding his harem. Most of the characters with good character development are the older ones, but after the loli's went rampant, the older ones weren't allowed much screen time. It probably would've been an easy 5 star if the author kept the loli's moderate and focused on other important things.
5. Repetitive Problems: the plot has so many repeating problems, such as the main character holding back during s*x, him adding everyone he has s*x with to the family, and Megumi b*tching. It's not just once or twice, but the problems are repeated too many times that it quite irritates you. Each iteration ends with you thinking "thank god, this problem is solved now", but the author shoves it back in your face before you could even forget about it.
6. Villains: all the villains in this novel are quite dumbed down and boringly comical. It makes the novel quite light-hearted, but it makes it less exciting at the same time as well.
7. Combat: the actual combat scenes are quite lackluster. They perform uninteresting skits instead of seriously fighting. Despite being in a modern setting, guns are rarely used. Close combat somehow dominates everything.

Our MC will slowly heal the trauma of his harem and [family]. His [Family] too will heal his trauma....
