He's put on loan to work as a guard to protect an Ojou-sama, who of course falls in love with him from the feelings of safety he invokes, along with the maid and a kyonyuu student.

At some point Qin Choa meets Su Jis father, who being the father in law will just absolutely not allow this relationship between his beloved daughter and a no name security guard who relies so much on brute force (makes sense to keep your daughter from getting in a relationship with someone who clearly invites mortal danger on a daily basis) to happen. Following the meeting a deal is made between the father and Qin, he has to make a small fortune without relying on force by a year time (which technically he fails since he got most of the money from what are basically assassinations. During this time Qin is forbidden to have contact with Su Ji, the latter goes studying aboard for the duration.
Qin goes around, and basically picks up girls one after another (harem tag - makes sense right?).

He joins a company and makes the coodere boss fall for him, followed by some girls who just fall after fighting him or seeing him fight. All the while he's telling himself he gots to do right by Su Ji, he's just putting the moves on any hot piece that needs some saving. Later his constant reminding himself becomes meaningless as the harem all meet and w/e starts to actively pursue others.
This all makes sense, its a harem. The problem I'm having is the way so many girls just drop on his lap, its gotten a bit out of hand. With all these new additions, they become bland and empty characters that the author just shoves into the harem. For all the proclamations of love towards Su Ji he spends more time chasing girls than the girl he supposedly pined for in a year of separation (in this case, distance did not make the heart grow fonder, just wander). The harem becomes so bland that I end up skipping entire portions that are dedicated to these new members and its alot.
And I get arrogance is a unchangeable aspect for these xianxia, but pretty much every time a harem member gets hurt its cause Qin is wasting time posturing, taunting, etc. Then the bad guy pulls a gun or magic and shoots the girl and he flips out like it was inconceivable. Proceeds to selfishly bring them back to life, which goes into Qin commonly beating on people just doing their job to get where he wants to go.

Well, when I checked some spoilers, his harem seems to have over 40 girls. Well that should get the readers pumped up to read this novel. And he does have s*x with a bunch of them (the s*x scenes don't have much description though)

My dude has a gf but he still mol*sts other girls but only mol*sts them, doesn't give them what they want and straight up uses them

My dude dates a girl, doesn't even kiss her but he mol*sts every attractive girl he sees, somehow making them all fall in love with him only to say I can't because of my girlfriend. Than later proceeds to cheat without a guilty conscious only to reject every other girls advances that he was sexually assaulting than continue to cheat with that girl he originally cheated with with a clear mind. Than once again ignores the other girls he is mol*sting only to r*pe a 16 year old girl... author, this here alone makes me beg you to stop writing. you can't write a romance harem like this. its not satisfying at all and leaves me feeling sick to my stomach.

Also my dude is a cultivator but decides to blatantly mu*der tens of mortal people and cripple hundreds more and feels accomplished... WHAT?!?!?!?!?! are you f*cking serious rn?

Back to the girl issues. My dude never kissed his gf but r*pes and cheats and mol*sts other girls and the author decides to write the gf out for 50 chapters only to bring her back than have her dad say no contact for a year and you better have a mortal job and earns tons of money.... once again he writes off the gf but decides to have the main character mol*st high school girls, college girls and even his bosses and police officers... Also the author writes off a ton of girls that he sexually assaults.

THE PLOT HOLES ARE REAL. My dude is the chairmen of the most power company, leader of the mafia in a town and a cultivator but you know, he goes around telling everyone he is a regular security guard and all the sh*t he accomplished never existed except for the fact that he kills a lot of mortals.

DONT READ THIS. DONT WASTE YOUR TIME LIKE I DID. THIS NOVEL IS HONESTLY tr*sh AND THE PERSON WHO WROTE THIS AND THE PEOPLE WHO LIKE THIS ARE SOMEWHAT f*ckED IN THE HEAD. When I see five stars and positive reviews I'm like, did you actually read this or is their something f*cked in your head?

Let's say, a woman ran up to you and calls you husband and you get to find that women is actually being chased by some hoodlums and you don't know sh*t about fighting, so what would you do. Would you fight them head on? You might even die or get some serious disability for your entire life, no but you want play a hero for a woman, who has dragged you into this mess in the first place. Also not only could you die, even the woman might be implicated, no but you want to play the hero, don't you!!! This is our MC in the first chapter.

Also he does ends up in the hospital and is not even angry at the woman. Sure, you want to play hero, but why the hell, are you not questioning her, about her wrongdoing!! He actually feels embarrassed, as the woman pays his hospital bills and helps him find a job. He also feels credited and wants to repay her because he is an honourable man, who doesn't want anyone to pay his bills and find him a job and did not play a hero for any type of gains. Man, you just saved her life, this is the least, she should do for you. She is rich, she could have easily given you a million dollars for saving her.

Let me tell you, this woman is a pain in the ass. She acts all haughty in front of MC, however, when it comes to some real action, she gets her ass saved by the MC all the time. She acts as if MC is the one who owes her and the f*cking MC acts the same. I know man, she is beautiful, but you need to reject her unreasonable demands. You know what, who cares, she is beautiful, so I will do anything for her. If there is even a slightest kindness shown to him by anyone, he would take it his heart, which is admirable, however when he does the same to them, it becomes meaningless. They remind him of they did for him but this guy becomes a complete idiot and just won't revolt against their claims. This guy saves most of their asses, however what he gets is nothing and gets dragged into an even bigger mess.

There is a brief international student exchange event and let’s just say the author pandered to the Chinese readers by demeaning the South Koreans and Japanese characters with stereotypes. Pretty minor, but it's there.
