There will be a feature in the future. His name will still be Lucerus, however you will get a chance to name the alias most other characters would use.(other than main heroines who will call him Lu). I am also considering using a nickname/petname for spicier relationships. Let me know your thoughts! ^^
I completely understand. Im not explaining it fully in hopes of avoiding spoilers, but the name you chose will be used quite a lot, especially during h scenes. Ill see if theres some way to incorporate your chosen name with the main heroines, maybe in more intimate scenes. However in normal scenes theyd usually refer to you as Lu, unless the context suits it. Thanks for your feedback,it gave me food for thought! ^^
