Nameless's Questions (4)

Hi guys, quite a few years ago I read a yahoo manga series about love stories of (I think three? Brother) each brother had their own mangas (each of them had like three or four mangas). I remember the most I think middle brother’s love story. He is a university student. He is tall shorter hair and I think he is also righteous as well. He develops a relationship with this guy (with longer black hair) who is known for promiscuity I think? This details is a bit hazy, all I remember is that the middle brother does not have the best opinion of him in the beginning but then really comes to love him and I think it takes the black haired guy some time to open up to him and to rust him and believe that he is loved. It is quite angsty. I remember really liking their story because of all the angst, does anyone know which mangas it could be by chance? The brother was seem and the black haired guy was Ike

Guys I read this manga years ago but then I lost it, maybe somebody can help? Here's the plot:

So a woman is a very good worker, always wears oants and even during sex she will answer her boss' calles. That has ruined a lot of her relationships, she is often compared to how a guy acts when working and (maybe I am not sure about this one) has a nickname related to this, like metal something? Idk. She has long hair, blonde. They get a new guy at work and for some reason they start a game-like bet, they have to please each other sexually and whoever pleases the other more wins. For example, the guy covers the girls eye and does cunni, she even screams because if the pleasure, later when she blows him the guy enjoys but doesn't scream because of the pleasure which makes the girl bummed out and makes her feel she lost. It's not Manhwa, it's definitely japanese manga.

This is all I remember, I really really hope somebody knows which manga I am talking about, I've been searching for it for years.

I am looking for bl mangas with enemies/rivals to lovers and some angst. Could you guys recommend me something?

Hii does anybody know the name of this manhwa I reallyyyy liked but can't remember the name:

It is set in Joseon Korea. The seme is from the
underworld, he takes lives when it's time. Once he exchanges an old man's life for his son, who dies instead of the old man. So the king of the underworld punishes him and sends him to the mortal world where he has a form of a puppy during the day. In the mortal world a young prince (uke) adopts the puppy. The prince has an evil stepmom who uses evil spirits so that the prince can't sleep and function properly. The underworld prince (seme) decides to help him.
