especially parts where he forces the targets to say ily to him as part of his task and the western fantasy world GRAGH GET IT OUT OF MY HEAD PLSJDKEHFIWHJRW

Even though the MC said he's attracted to men, there's no ML... I admit that I suspected the system for a second, but neither the MC or the system are interested in one another like that, hahahahaha

So that's also the reason why all the arcs take place in BL settings.

1 - MC wakes up in a cultivation world, having been stabbed by his fiancee, who is weaker than him. He captures a cultivator to asks questions about this world (his system hasn't arrived yet) and accepts an assignment to kiil the new fiancee of his ex. By making him believe his ex is responsible for stabbing him, he gets an assignment to kill his ex. When his sytem arrives, he receives the assignment to let his ex fall in love with him and tell him he loves him. He changes his appearance and into that of the new fiancee and visits his ex. He shows his real appearance, stabs his ex and lets him tell him that he loves him. Mission accomplished, MC travels and enjoys the world 300 years until he runs out of money and goes to the next world.

2 - MC is now in a martial arts world. MC was the son of the leaders of the martial arts alliance and his family was a powerful martial arts clan. During his travels he fell in love with a man and insisted on marrying him. However his future husband turned out to be a leader of a demonic sect and drugged everyone at the party, killing everyone there. His mission goal is to get revenge on the sect, make his fiancee regret what he did and let him marry MC. He accepts a hit to kill fiancees right hand and puts the same drug as used on his wedding banquet in the body's foot and enters the sect who are having a competition. He explodes the body, rendering everybody powerless, forcing ex to marry him by killing his subordinates making him say he regrets and killing everyone from the sect.

3 - MC has been forced to be the lover of a 2nd gen rich boy because he looks like his white moonlight. He is thrown away when WM returns. His mission is to get rid of the stand-in status, make scum profess his love and make him feel what MC felt. MC finds the ex's competitor and convinces him to pay for a hit and tortures and kills ex. Then he convinces WM to pay for disfiguring himself and enjoys several years in this world becoming a member of an assassination organisation.

4 - MC is now a eunuch who has helped the present emperor get the throne. Afraid of his influence he framed MC and killed his entire family, leaving MC alive and sent as a concubine to concubine Lin. His mission is to let scum pay back what he owes (throne and feelings should be returned) and beg him (to help him). He convinces concubine Lin he will help her and her general father, spreads rumors about a ghost appearing and when emperor is sick in bed in regret and fear lets him beg MC to take him with him to the afterlife. Afterwards he kills him and spends the money he took (general refused to pay and wanted to kill him) in 1 1/2 years.

5 - MC wakes up in a futuristic world as an omega with an S-level mental power (the highest). The man he fell in love with had his glands removed and put into his white moonlight, a beta B-level woman, who becomes an A-level omega afterwards. MC became an A-level beta after the surgery. His mission is to retaliate against WM, prevent her from marrying MC's beloved and let him marry MC and become a famous person beyond the stars. MC starts sucking up to the new fiancee's family and gives them an advanced Zerg as trophee. He goes to the wedding between ex and new fiancee and brings along the Zerg queen whom he's fed a medicine to hide her presence filled with nanobombs, dressed up as a human. He then objects to the marriage and lets the Zerg Queen kill the guests at the wedding demanding to be married to the ex. He also demands a huge pay for saving the prince who is present as a guest. He immediately becomes famous in the universe (wedding is on TV) and after the wedding he kills ex and bombs the Zerg Queen with the fiancee. He escapes and spends decades as a space hitman.

After that he died in an experiment and MC appears. Mission is to let all his exes tell MC they love him and repent and take everything back they got from MC.

MC travels to the kingdom of his first love and finds out that he has died a long time ago. He decides to resurrect him as a ghost and ties him to a ring then tells him he needs money because he spent a lot resurrecting him and lets him kill people for payment. After a while he brings him along and finds his 2nd love. He lets the ghost distract them and hunt the moonlight towards him. He then kills the moonlight wnd take back what he got. Afterwards he pretends to save the ex to let him profess his love. Then he orders the ghost to kill him and takes back the sword the ex made from his bone. He travels back to his tower and feeds his ex-disciple something to make him drunk, lets him profess his love and make everyone believe he r*aped ghost and then throw him out of the tower telling everyone he is ashamed of him and kills him. Ythen he spends a 100 years as a contract killer, killing people and enjoy life.
