Yosano as a first executive in Port Mafia knows you too well, you - Mori's child. And of course if he was your father he was abusing you, making you into "perfect weapon". Yosano was with you after attempting, maybe not after your first but then she was. Always helping to time when she run from Mafia to Agency. Left you. And after that your contacts and friendship broke up, into bad one

after some years

You were rested in some dark alley after rought mission but ... she found herself there too. Yosano looked at you and then that smirk, not like always, maybe mean now?

Yosano: "Oh, I thought you'll cut off your veins to eighteen but look at you, still standing."
