In the original life, MC was a succubus who pretended to be a human priest. ML is the OG god but he disguises (? Or awakens) himself, as an envoy. They end up doing the deed and agree to be bfs, but ML has to go create more world. The original world falls on chaos and MC's soul disappears. ML finds it but it's barely there so he ends up creating a lot more worlds to gain power to help MC's soul. He ends up giving power to rebirth MC but ends up falling asleep from lack of energy. Half of his soul gets distributed in the worlds to find if MC was alive, but the him in the worlds kept waiting and turned villainous. The other half created the space where the system is and so he rests there. The original first arc ML kept giving aphrodisiac to MC as revenge and was always kinda disgusted sleeping with him until the near endish. Honestly it didn't match the theme of the story. The rewrite is better, in which MC and ML develop a better relationship.

In Arc I ML was abusive and used aphrodisiac on MC to torture him, MC first woke up in a warehouse and when he was promised to be gang-r*ped he was like - yeah, come on, I'm ready. I honestly don't remember anything then them later only rolling in the sheets. In Arc II is mostly kept in a room, ML comes to him in quite an unconscious state, MC doesn't mind, although he doesn't even know who he sleeps with, also continues to flirt with whoever, story is plain AF. Arc II I forgot what it was about. It was still on-going and I dropped it.

whenever the ML is remorseful is more than the beginning of each arc.

Yes the dog blood isn't heavy. So if you're looking for angst this is not for you

I notice that each arc has similar story line like ML will despise at the same time feel attraction (but ML didn't know that its love at first sight) to Chu Xia at first, and will become possessive, then Chu Xia will be in danger and ML will finally recognize his feelings and then fell into deep remorse.. At the end Chu Xia will comeback and they'll live happily ever after.

Altho the story line is repetitive the novel is not boring

ML is God and they've met before when MC is succubus. Something happen which made MC's soul almost gone so ML made many worlds and divide his half soul to those thousands world to wait and meet MC's soul (i don't really understand this part since its MTL) while the other half fell asleep. The villains are ML's scattered souls and in the last arc they've finally met as God and succubus (back of their first meeting I suppose). It's happy end :D
