Read 1000 Manga Or More

Help please! I'm looking for this manga, there's yakuza and intelligent agent, yakuza(uke) wants to make the agent (seme) to be part of yakuza bc the boss like his intellectual. but the uke end up falling in love with him, At first the uke still feel owe to yakuza boss so he leave the seme, but the seme pick him up and so they live together.
There's another couples too, like the leader of agent have a lover who can do martial art(uke) and the uke will end up being a partner with the uke from the first story (uke x uke).
And another couple, abt the traumatic partner being with his senpai which his senpai protected the girl client and end up will married her, but now the partner have a new partner and worry abt his new partner carelessly but end up together with him. Ahh the senpai now in document section (or whatever it is) not in action section again(idk the name) ┗( T﹏T )┛
