I'll first describe the proccess by memory then ask you a question.
Firstly you just play the game as normal and complete most of the quests from Noer, including the one where you rescue Cecily; After sleeping a night on the inn there'll be a green ! on the guild quest giver at the tavern, you talk to him and you'll get Milo's invite (the first) at your notes at the menu and you'll receive a pass that allows you to go the noble region of Noer, where Milo'll be waiting for you at the golden bar there; You go there and he'll give you the quest to assassinate Adam; You can complete the quest by either killing him or sparing him, and then telling news of your effort to Milo (if you kill Adam he'll drop his head, which you need to take to Milo);
After completing that quest ^ and some time passing, Cecily will have the green ! signalling she has a quest for you, you need to talk to her and she'll explain it to you, but not allow you to accept it yet, saying it's dangerous and that you should take some time to think, specifically 5 days. During the wait or after it, if you killed Adam on the previous quest, after sleeping at the tavern (how it went for me) there'll be a green ! on the guild quest giver again, that's the second invite. If you spared Adam, I believe Milo will not enter in contact with you again, so you'd need to go back a few saves and redo the quest by killing Adam.
After taking it remember to save before talking to Milo, as it's easy to refuse it by accident.
So did you kill or spare Adam?
