It a world hopping story with a unique base.

When the main character (Lu Heng) first wakes up in his client’s (Reiner Hart) world, the face he sees is not his client’s but his own made to look similar to his client. I’m assuming that Lu Heng was suppose to wake up in Reiner’s body it was suppose to look exactly like Reiner, and the fact that Lu Heng didn’t was a major issue — hence why both the main character and his system are worried and confused.

The first arc is an ABO with the zerg setting (if you read FOD) and the MC is a beta. He is the childhood friend and adjutant of the world's ML (he is a superior) and the world's protagonist is a new member of their squad. Protagonist is an omega who conceal himself as a beta. Then stuff happen and ML is inlove with the MC and caused his overall score be changed from an A to 'pending'. Lol haha

Second arc is currently being translated, but the story goes as a demon king (mc) who wants to protect the demons and adopted a white demon rabbit (female lead/protag). The protag was caught by a cultivation sect and set a trap for MC but failed as he came prepared and suffers from an amnesia and was temporarily taken care of by a monk (ML)

The ML was actually in love with the MC even before the transmigration.

Yeah, B****es! The ML was f*cking in love with his childhood friend! And in the original story, he WAS in love. But along the time, he was slowly disappointed with the original owner's shift of personality to be more and more against their original owner-

WHICH IS not willingly, you must note. The original soul shifted his personality to be pro-government rather than the military is because he knew they're treading in the narrow cliff, and their squad is a special squad that is too famous for its own good. The original soul knew that if he didn't quickly maintain a balance, some people above would probably get rid of them, hence, he was being pro-gov to maintain that balance even in the face of his bestfriend's disappointment.

The original soul know his bestfriend was too much of a free soul and want him to stay that way, and instead sacrifice himself to be a strict, rule-abiding, cold robot. Which was a huge leapt of personality in ML's opinion, as the original soul was actually very playful, naughty, and fun, The ML even stated that all the mischievous 'fun' ideas of rebellion back in their academy days were all proposed by the original soul. Hence, probably why the ML fell for the original soul even way before the MC transmigrated over.

In the original story, the ML grew more and more disappointed to the original soul and their misunderstanding was not cleared. he instead came to fall in love with an omega while having a fall-out with his bestfriend, they were 'torn apart' by the original soul because Omega wasn't allowed in a military (unless they removed their gland). And the bestfriends split up in bad term, in a deadly fight against alien race, the bestfriend duo weren't together and the ML was too devastated over the loss of the Omega Supposed-Protagonist, before the S-P ran to help and with their love they managed to save the day, condemning the bestfriend at the end of the day, forcing him to die in vain.

In the fixed story with the MC, however, the MC conveyed the real reason why 'him' (meaning the original soul) did all those things and the ML was touched that his mischievous bestfriend being so restrained and rule-abiding for his sake. And they ended up to never had a fall-out, the ML stayed in love with the MC ('s skin, really). Communication is indeed the key. But still, their story was fated to end in tragedy.

AAAH!! If only the original Reiner spoke up and explained himself, my ship would probably set sail far away, without even the need of someone to transmigrate over! I'm adopting those two bestfriends! I'll make sure they'll get their own story which end happily without a transmigrator helping them through! I'll write something that has Hewitt (XiuYiTe) to reincarnate back to their childhood or something! My original Reiner couldn't be dead this way!
