If you have looked at this game with save editor you may get a good idea what at least one of the major branch choices will entail, I will put it down below in spoiler for people who do not want to know.

If correct assumption from me it will mean there will indeed be a full harem path and a path where you may share some with Danny in future. Considering the past, Morrigan is the agent of corruption and her entering through Danny is the devs choice. He could have chosen differently, but may have had his reasons.
