Little weird to not want to be thought less of, then spill out that you're a masochistic bottom right after. Way to go luxi lol.
It's a little odd but I feel like the two concepts are disconnected from each other. Like she wants to be degraded and controlled for sex, but day to day she doesn't want to be thought less of for having a past as a complete pushover dog.
Yeah, it's this. Two different contexts. A bedroom scene where she's a masochistic dog has the security of knowing it's part of the emotional intimacy of the relationship. Revealing she's been a masochistic dog to get someone to look her way and asking for it in the bedroom are both things that have the risk of destroying that intimacy.
this ^^^
In the bedroom she wants to be treated like a dog, but that doesn't mean she wants to be treated like this in day to day life; the whole point about it staying in the bedroom is that it's ultimately a fantasy. The difference between Luxi w/Tongtong vs. w/purple hair is, presumably as we don't know a Lot about purple hair, how Luxi is actively consenting now.
Props to the author for not going for the classic drawn out miscommunication plot line btw, it's so much more realistic/healthy for them to immediately communicate.
