A Yaoi, the Uke is OP or just strong and often protects the Seme / fights side by side with him / anything like that. Preferably the world is a cultivation or an awakeners-esque system-esque world.
I kind of want the Uke to be a bit more of the brash type. I also would prefer it if the Uke is muscular. Body build doesn't matter too much- if he's a big dude that's cool, if he's tall and slim but muscular, thats good too. I just don't want him to look like a lil twig- you can still recommend those and I might enjoy it- its just not necessarily what I am currently in the mood for, essentially.

THE SECOND COUPLE IN THIS PLEASE
https://www.mangago.zone/read-manga/wolf_in_the_house/

A Yaoi (preferably, but not necessary) with an office / any hierarchy setting.
The 'Boss' overworks everyone / is hated (and/or) has a bad rep.
Perhaps is kind (and/or) works 10x more then them and is harsher on theirself. [unbenownst to most others]
Perhaps the love interest also hates this boss-esque character at first but slowly learns about and falls for her/him.
Just anything sort of like like that.

stuff featuring a weak female lead (FL) in an otome setting who gains power through a system (or otherwise), eventually becoming OP. Ideally, she grows alongside a lover—who can be male or female—who is either her equal, weaker, or complements her strengths and weaknesses.
Alternatively, I’m interested in male protagonists with a "Death is the Only Ending for the Villainess" vibe, incorporating elements of angst, suffering, tragedy, and sad backstories. Yaoi or non-yaoi are both fine.
A Yaoi otome where ML is a top but acts like the typical bottom or the opposite would be cool too.

Fits your second request, except he actually faked his tragic backstory, because our mc is a scheming villain, but none of the other characters knows that, not even his love interest (BL)

While it’s not an otome game setting(but there is a love triangle situation), nor is there a system involved (she gets stronger on her own), this one matches all you’re asking for and I quite enjoyed reading it!

1. A yaoi where the uke is op/powerful/stronger than the seme. They could also be switches too. I just want the one who bottoms more often to be strong.
2. A manga (preferably yaoi) where its an office setting or something of that sort where the boss is hated because everyone thinks he is harsh but he is actually harsher to himself and works really hard. Perhaps some angst.
3. Yaoi mangas with proper plot or system type stuff or fantasy with some stat building or getting stronger being a part of the focus. Kind of like 'How to survive as player' or 'I can see your stats'

Welp here are my recs!!

For the first one I don’t know if this counts because they are both strong but the uke is slightly better at the profession they are both in
https://www.mangago.zone/read-manga/contradict/

I can't remember the name but basically the FL lives with her mom who is kind of abusive and she reincarnates or something of the sort and at some point somewhere in the beginning she goes to the temple to meet a duke (probably of the north) and she offers him an alliance and basically calls herself a useful tool or something
I'll add onto this: Before she went back in time the FL was basically a tool used by her brother or fiance or something but eventually when she lost her use he cut off her tongue and I think her limbs too and then the Duke found her like that and basically she ends up deciding to help the Duke because of her guilt since basically the brother or fiance was against the Duke and there was an entire war situation or whatever.
She ends up basically gnawing at her tongue and drawing a spell circle on the ground with her blood and activates it and dies and goes back in time.

Is there a Manga for "How to Live as the Enemy Prince"
( https://www.lightnovelpub.com/novel/how-to-live-as-the-enemy-prince-17031322)
or something Similar?
Doesn't matter if its Manga or Light Novel for the "something similar" part.

Any Manga (or Light Novel or Novel or Fanfic or just anything)
where the Main Character is a Male and (whether transmigrated or not) is labeled a Villain but e got some kinda Tragic Backstory or some Shiz and/or e has Morals to some extend maybe and we explore that crap- (I use 'e' as a Neutral Pronoun)
Also if possible don't want overly weak MC-
Just anywhere above weakling is good, doesn't have to be, but can be OP, generally tho, just want a Healthy, okay individual.
I just need Angst and bitter sweetness and happiness and to feel Generally like crap while also feeling good at times.
I don't care too much if there is romance, whether is gay or straight or poly or whatever.
Would prefer no romance and just comfort and stuff but Don't care to much.
JUST BRING ME PAIN.
Thank You-
Doesn't have to have all I stated- I Just Rant- Anyway-
U probably get what I'm trying to express by now-
So I shall sit here in silence... uhm- Yeah...

Mo Dao Zu Shi ( https://www.mangago.zone/read-manga/mo_dao_zu_shi_novel/) definitely fits what you're looking for. I would recommend reading the light novel over the manga.
I'm also gonna recommend the light novel Spring Trees and Sunset Clouds, even though it's not quite what you're looking for. It fits your vibe of angst, bitter-sweetness, and happiness, and the MC's backstory is definitely tragic. The MC is physically very weak though.

I'll check out the Light Novel in a bit probably, I read a summary or description or whatever for it and It feels like something I could probably enjoy, but would probably also be something I wouldn't read very often- It feels like the type of story I would read a bit of every once in a while but not binge through cuz I would Die if I did-
That opinion IS just based off the description though so Possibly inaccurate-
I'll find out when I begin reading it.
For manga I was kind of looking for things that give more of a
"Death Is The Only Ending For The Villainess"
or
"When the Villainess Loves"
or other of that kind of thing vibe,
Also, already read some of Mo Dao Zu Shi, it was alright mostly, I got a bit bored after a bit and dropped it but I'll probably check it out again at some point.
Thankz for Recommend, uh...
I shall go read things and Un-do my boredom, uh...
T(h)ank you-

Any mangas where all teh Male Leads end up happy even if they don't end up with teh female lead?
Or a Manga where its a Dood and 2 girls who fight over him and he the MC and he just like "I'm so Confused" and teh wamen are the flirty ones and the dood is the innocent blushy one, but he doesn't look like child and looks fairly big man while still being adorable and also Stronk?

Are there any Mangas at all where its just a Fekin OP Wamen doin thangs and bein STRONK AS FEK and she stronger or just as stronk as dood,
whether its with swordsmanship or smarts she can match em perfectly
and its not like "Oooh I have a magical powaaarrrr and now I OP WaaaOoww"
and more like "I worked really hard and now OP badass QUEEN"
or "I supa stronk but Hide my powa!!!"
I'm looking for a manga or wuxia or whatever where the MC shapeshifts, has multiple identities with distinct appearances, all are perhaps powerful in some way & MC only has one lover. No matter what shape they take their lover stays the same. Also I want them to have both female and male shapeshift forms all powerful in some way in their own right. If MC can also clone themself so these shapeshift forms can live individual lives thats cool too.
Just shape shift and multiple idententities is the main thing. Some underdog vibes. Maybe messing with ppl by making them think he/she is their own partner. Idk. Just some fun face slapping and multi identity stuff. OP vibes preferably but like hidden power vibes.
