 (Plum 🌸) is a very popular piece of Honkai: Star Rail fan art featuring the yuri (girls' love) ship between Stelle and Firefly (commonly called "Stellefly").The main caption in Japanese reads:
JK𝙨𝙩𝙚𝙡𝙡𝙚𝙛𝙡𝙮…////
ホタルちゃんをいじめるな！！ (English translation: "JK Stellefly…//// Stop bullying Firefly-chan!!")
  • "JK" here most likely stands for "Joshi Kousei" (female high-school student), meaning it's an AU (alternate universe) where the characters are depicted as high-school girls.
  • The artwork has gained massive traction: over 139,000 likes, 31,700 bookmarks, and 2.68 million views as of January 17–18, 2026.
The attached image is a three-panel comic-style illustration:
  1. First panel: Firefly (in school uniform) is sitting/lying on her back looking surprised and flustered. Stelle is leaning over her very closely, almost pinning her down, with a teasing/playful smirk. Their faces are extremely close. Firefly is blushing hard and seems overwhelmed.
  2. Second panel: Stelle gets even closer — their hips/lower bodies are pressed together. Stelle has a mischievous expression, while Firefly looks even more embarrassed and is covering her mouth or trying to hold back a reaction. The "bullying/teasing" vibe is very strong here, with heavy blushing and suggestive closeness.
  3. Third panel: Firefly is completely red-faced, eyes wide, possibly emitting sparkles or looking like she's about to "short-circuit" from embarrassment/cuteness overload. Stelle still has that cheeky grin, clearly enjoying how much she's flustering her girlfriend.
The overall tone is playful teasing + affectionate yuri fanservice — very typical of the Stellefly dynamic in the fandom, where Stelle is often portrayed as the bold/teasing one and Firefly as the easily-flustered, sweet one.Many people in the replies loved it, with some calling it "god-tier" content or reacting with flustered emojis and fan art redraws. There are also English-translated edit versions floating around in the thread.Super cute and very well-received piece of fan art if you're into Honkai: Star Rail yuri ships! 😊
