Tengoku Manabu (Seme) (Younger) x Aoki (Uke) (Older)
I like the psychological aspect of this manga with Tengoku kind of manipulating Aoki. I also really liked seeing Aoki's childhood and how his mother played a role in how he acts now. I'm glad they managed to work things out later and understand why one person acts like this and how they reassure one another.
2nd couple (Ch. 16 - 33)
3rd couple (Ch. 34 - ongoing)
The 2nd couple is so interesting because it's basically a very selfish seme and a uke who at first was in love with the seme but eventually moved on and now just tolerates the seme. This is kind of unique since I never really seen the uke moving on in this way, usually they still have lingering feelings and this uke also has that but he knows better than to act on it and only hangs out with the seme because they were old friends.
Alex (Seme, blond) x Clark (Uke, Black hair)
This is the psychological thriller where the uke is not the usual small uke that needs saving but instead Clark is the one trying to save his friend/ex by manipulating Alex (the killer) into falling in love with him instead. I really like Clark and how cold and calculated he is. The way he acts and thinks is so interesting where his indifference almost makes him seem like a potential serial killer. I also like the Inspector Chief and his shamlessness
Makoto (Seme) (Blond hair) x Ai (Uke) (Black hair)
The relationship between the 2 brothers is so messed up yet intimate. It's interesting to see how both of them try to possess one another in their own way whether they realized it or not. And also there were so many plot twist regarding the main characters relationship with other side characters that it will make you doubt every single one of them. Basically you cannot trust anyone in this story, they all have their own version of it.
Uncle (Seme) x Chouno (Uke)
TW: Pedophilia, grooming
This is prequel to "Chou to Hana no Kankeisei". Poor Chouno just wanted familial love from his uncle (mother's boyfriend not actually related) but the uncle twisted it to the same love he had for his mother. He slowly groomed Chouno to only need him and to be incapable of doing and deciding anything without him. But then he got scared when Chouno was the one who decided to stay with him so I really don't know how I feel about the uncle.
Lief (Seme) x Ross (Uke, Priest)
Ross straight up looks like Bruce Wayne. Not gonna lie that's why I kinda like this story. Also taller and bigger ukes are always a plus. It's not that messed up but actually it's more wholesome than anything. I just added it here since it was tagged as psychological.
Baek Ryong (Seme, long white hair) x Jeon Doo In (beefy uke, black hair) [The daddies couple]
Chapter: 13-15, 27-28, 30
Not the main couple but I find that their dynamic is even more interesting than the other two couples' dynamic which are basically abuse and manipulation not that this couple doesn't have that but their interactions are really amusing while the other 2 couple's are just sad. I like how dominant Doo In is when he is with Baek Ryong but he is a really bad father to Miho.
Shindou (Seme) x Cyborg (Uke)
There are some unsettling concepts in this story like how they want to sell a sex bot who is basically a young boy and that there are creepy old man who don't really care about that. But the seme himself is a pretty moral guy so he knows this is all pretty messed up but he can't get out of it due to his pushy friend. He's very reluctant to do anything at all so he just does the bare minimum. The interaction between the seme and cyborg becomes very wholesome later.
Shiro (Seme, white hair) x Kei (Uke, black hair)
Though it is yaoi, I don't believe there was any explicit scenes between them besides if I remember correctly Shiro teaching Kei about sex. This story involves prostitution and shows a little bit about its dark side. These 2 don't really fall for each other but are more like a platonic relationship even at the end. Also you can't help but feel for Shiro at the end and his delusions. Joe's story is pretty realistic too.
1st couple: Older brother x little brother
I only read the 1st couple since the others didn't interest me but what I read is kinda messed up. There is incest with the older bro slowly falling in love with his little bro first when he was taking care of him with little bro following suit. It's kinda really uncomfortable because he practically sexualised everything that was innocent though he kept it to himself because he knew it was wrong and only did it because the little bro initiate
