Review Detail of BotBrain in Nanomancer Reborn - I've Become A Snow Girl?

I fell in love with this WN almost immediately. The premise of an OP protag reincarnating into a weak body and cultivating isn’t new BUT it sets itself apart by focusing on how the protag uses her experience to teach her new found friends and help them cultivate—at least initially. The story takes a severely downward turn in the latter half (around chp700 I believe) where it completely butchers the core friendship storyline it was developing in favor of a romance and abruptly neuters the protag’s power level for the sake of it. I won’t spoil anything, but the protag literallt never loses a fight (by which I mean get severely injured or need assistance) until the love interest becomes prevalent and then she suddenly gets injured for the sake of this love interest taking character EVERY TIME the love interest is in the story arc, without fail. The worst part was that it was developing with the concept of “I need to learn to trust the friends I cultivated” but it throws it out the window for “Conveniently strong love interest saves the day while my friends are useless”. Utterly dissapointing with how it develops but the start of the novel is amazing and it’s well written. If you don’t mind the romance, I highly recommend.
