Longer Summary: It's been 8 years since Reina, the stoic yet cool silver-haired protagonist, has been suddenly transmigrated as a girl into a generic tower-climbing novel that's she's read several times over. While having to cautious around the regressor MC who's sensitive to any variables (and almost deciding to kill her as a result) she and the advance party have been stuck on the 150th floor of the tower, having failed the raid several times now. While recovering in the hospital, agitated and depressed over the repeated failure:

"F*ck... Should I... more>> retire?"

Suddenly sees a prompt appears

"Constellation Community Login"

"... Huh?"

[Is it true that Reina's retiring?]

[If Reina retires, I'm leaving the gallery for real lol]

[This time, give her a weapon instead of armor... I'm begging you, Constellations]

[What's Kim Ji-eun doing while Reina's considering retirement?]

[Reina's 150th Floor Raid Tips (Incomplete) ]

"What is this?"

Review (TL;DR at the bottom) :

I'm generally not a fan of novels that involve a gallery because they often feel like they're unnecessary to the plot and just there to bring up the word count. I Infiltrated My Fan Gallery Created By The Constellations is quite the exception in that adds more to the story in a good way. It's entertaining to see how the constellations act and think of Reina. Serpina, the elegant and noble constellation who's always stern and strict? Turns out she's a yuri-lover who constantly tries to ship her with long-time comrade Kim Ji-eun. Perbas, the arrogant constellation who always looks down on her? He's actually an affectionate senior who's constantly worried about her in critical moments. Aside from that Fate Road, the name of the gallery/community system, ends up being a vitally important source of knowledge and information for Reina, becoming instrumental to her growth where her patchy knowledge of the Tower and her own lack of talent is starting to reach the end what she can achieve on her own.

Throughout the story Reina gradually grows both as a challenger and in character development. With the help of the constellation strategy guides she slowly changes her combat style and grows stronger while learning the truth of the existence of her own gallery she starts to change her own thoughts and mindset. Rather than just mundanely training 24/7 or constantly wearing drab boring tracksuits all the time she starts to think and act more openly whether for the sake of increasing her own fandom, thus giving herself more help from the constellation, or being more grateful to them or her comrades.

The character dynamic between Reina and Jung Chan-soo, the regressor MC, is somewhat similar to Omniscient Reader. While at first Reina's only been focusing on survival (and not being killed by the anxious regressor) and clearing the tower, she gradually changes her own goal to become a rival or later on to what comes after completing the tower.

Personally one of the things I like most about Reina is when she's often embarrassed or flustered especially when it comes to how people are often trying to get her to dress/act more like a woman or when ever she accidentally ends up dropping bait for the romance-shipping constellations. One example is how Jung Chan-soo often says potentially misleading remarks about Reina that people often mistake it for affection.

Other characters in the story are also well written with their own character development whether it's Jung Chan-soo's near-paranoia to any variables to his regression or the unknown future, Kim Ji-eun's affection for Reina and her fear of being abandoned, or Lee Se-jin, one of the regressor's harem member, being afraid of the different treatment Reina receives from him compared to herself.

The overall progress of the story is ideal and consistent in my opinion. It's not progressing too fast that it feels like I'm missing any part of the story but it's also not slow that I feel the author's dragging out the story or running out of material to write. The story focuses on many different things without being confusing and flows well whether it's how Reina's working on training and growing, climbing the tower, dealing with other factions, interacting with other characters or dealing with the constellations.

TL;DR Very good story that I would highly recommend others to read especially if they're a fan of gender bender novels or like stories that involves the MC having to deal with a regressor like in Omniscient Reader. The story's well-written with good pacing, characters all have their own personality and development, and Reina, the MC, is very entertaining to read and follow throughout the story.
