no. there isn't,it is just a father-daughter-relationship.
he is just treating her like any other father would, especially when his spouse/mother/lover who gave birth to her is deceased
AKA: equating certain traits that she caries to the once her mother did,relating to parts of himself that she sees in her, praising her when she does a good job, Helping her when she needs it. etc. etc.
its just how a father should normally treat there daughter, except Claude has a lot of unresolved with grief surrounding athy's mother and keeps seeing parts of her showing up in athy. Because she is a living memento of her life and then eventual death.
nothing that is happening should be taken romantically, and if it is heading that way i would stop reading immediately, because that is incest, and really really gross.
I'm really confused... guys... no judgment.. is it just me or is there romance vibe from Claude and Athy??
This is driving me nuts lol. I don't mind either way... i just need to know who to root for hahaha
Also, is this a light novel or just a web tool?
