Please Help Me Find This Manga

Hi people!
I'm trying to at least trying to redo my "already read" list (which has few titles compared to others) but I can't find one title no matter what...

It was straight smut with an archmage betraying his party bc the boy hero, the girl paladin and the saintess mistreated him. The archmage was called something like "Pastrache"(?) and he joined hands with the evil lord (or demon king) who's an old guy who give him an innocent succubus as his sidekick

I don't know anything about it cause I let it marinateTT. It was a rather new manhwa, the cover had like the brown haired male mc with like a child on his back or smth and many children scattered around in the background. It was like an orangish vibe, like you know the color covering it and....that's basically it

I really can't remember anything about it but it's a female mc that is like very smart she was transmigrated and the fl of the place she transmigrated to was obsessive towards her ml while our mc and her ml got together and then the fl's ml got tired of her whining and he was ' oh I want her...'(our mc) and they met in a garden or something after the story's fl poured tea on herself or smth..idk I'm tired

It was a manhwa where superheroes exist and there was a school for children with superpowers and the Mc is in the class where they put kids with 'useless' superpowers. They get a crazy teacher and kidnap the president and turns out the superhumans working for the president tried to kill him or smth so basically the kids saved the president. And the Mc had like the ability to know birthdays. It was rlly wholesome I hope I find it! ^^

So as the title says I want to find this manga, it has similar art style as "A far away home" manga, it had 6 chapters, the characters met in a bar or a club, I guess? The bottom looks like jin from "under the green light" and the top was very pretty he had thick eyelashes and big pouty lips, they both had black hair, it was very popular on the other site (yes the bat one) I remember that the bottom shared his traumatic past, oh also they were both mainly and muscular not like the pretty bottom troup. Yup that's all I remember if you know the name or anything similar please share the name and feel free to ask more questions I might remember more about it, I guess?

I need help finding this manhwa, all I remember is that when the mc was a child I think, they were in a carriage in the side of a cliff and it was snowing and the carriage fell off and his parents died but he didn't and someone came and took a ring off the dead parent's finger.
