* Genji is very angry and hurt by the adultery of his young wife with his nephew. BUT when faced with the obviously devastated and conscience stricken youngsters Genji is full of sympathy and nothing but kind. It's not his fault that that just makes them feel worse.
* Rather sweetly no matter how many years an affair has been over Genji can call on a former lover and find himself remembering his all old feelings and be eager to start up with her again. Usually his better judgement - or more often hers - prevents it.
* A woman Genji initially pursued was treated as a ButtMonkey by others including Genji himself. By their conventional standards she is not only unattractive looking, but she cannot do poetry properly (which was considered social status hobby during the Heian era). Regardless, Genji met her again after several years when she's on the brink of financial struggle and decided to take her under his wings along with several of his concubines.
* In chapter 26, there is a comedic scene of To no Chujo interacting with his long lost younger daughter whom he found. He expressed disappointment in her due to their unladylike and obvious childish behavior, but appreciated her devotion to her newly dad. Said daughter also wrote a poem to her new half-sister with unprofessional skill who ended up being amused by it and responded to her in the same manner.
