There is an ongoing anime about that (well, second season of it). Where the girl pretends to help out a guy socialize by teaching him fashion, behaviour models, how to talk to people and so on but in reality she is just grooming him to be her perfect handcrafted boyfriend. I bet Lia watched it and went "I could do the same to Uruka!"
(the red headed kouhai from the part time job is the best girl)
