I think this will be good Chidori is not hung up on the past or anything but it is having some effect on her, Senpai must have done some shitty things to her thats having some impact on Chidori thats why she probably holds herself back and is scared of others finding out, but now Chidori has a girlfriend that loves her and broke her fear of "loving other girls is wrong no one will reciprocate my feelings" and shes grown into a stronger girl im sure she'll be able to throw her past behind and move forward with Nanoha.
