Hakidame to Tsuru
Ten years after escaping AV, which he fell into paying off debt after being left by his Yakuza lover, 35 year old Kei is working part-time jobs to make ends meet. At a movie theater, he meets Junta, 12 years his junior and earnest in his love, but Kei's past is not something he's willing to share and he's afraid to fall in love again.
I Want to Spoil Ikurou-san
Gokudou Darling
I was about to drop this, but the chapter I was on turned out to be the last. It's not bad, just didn't really grab me. A proud man who has lost his mother refuses to accept money from his wealthy step family, who turn out to be yakuza. His step brother is into him; his other step brother assaults him. It missed a mark somewhere for me.
Memento Scarlet
An ex cop who shot his partner comes back to the special task force to help track down a serial killer, and is partnered with a loose, shady detective who is actually a double agent for the yakuza. If you're looking for a fluffy, happy romance, this isn't it. They fall for each other, but Kairi sleeps around for information and it doesn't look like he's going to stop. But they had a cool and open relationship, and they really seemed into each other! I'm a little confused on the case details.
Warudakumi Ni Mo Hana Wa Furu
The continuation of the story between the guy obsessed with money and the guy who got rich so they could be together. Also features a two-chapter story about a man (Takao's best friend who pretended to cheat with his wife in the other story) who falls for a kid he meets on the train. I would've *loved* that to be the main story and 10x the length. Really good potential for character development. Too rushed for 2 chapters but still a nice ending.
Yakuza-sama no Omocha
Naked Sword and the Tree Peony of Black
Kengou's childhood friend Touma refuses to part from him, becoming a lawyer and eventually scheming his way into the yakuza in spite of Kengou's resistance. The one with the sake cups semen joke, which...tbh I thought was kinda hot.
Tie Me, Unravel Me, Kiss Me
A tailor determined to stay in his deteriorating neighborhood finds it hard when gangsters show up, determined to ruin it. But a childhood friend reappears and might be able to help. I prefer this author's story "Get the key to my heart" over this, but this was cute.
Moon and Sun(Abe Akane)
The spin-off to Hana and Ikkun's story. Hana's Master falls for the foul-mouthed grandson of a yakuza. September 2020 ETA: Raising this to full stars on re-read.
