At fifteen, Gu Xiuhan rescued a young mermaid from alien invaders. As the last surviving mermaid royal in the entire star system, Ruan Yu was entrusted by the research institute to the Gu family, who had the means to provide care and protection. Since then, Gu Xiuhan was relentlessly clung to by this sticky, sweet, milky little fish. The chubby, short-tailed youngling Ruan Yu wriggled into Gu Xiuhan’s arms, pressing his little face into the crook of his shoulder and gripping his collar, refusing to let go. Earnestly, he imparted his "mermaid childcare wisdom": "You have to hold me, or the ocean currents will sweep me away." Gu Xiuhan: "?" …What ocean currents? —— In Ruan Yu’s eyes, Gu Xiuhan had always been as cold and rigid as a war machine. Silent, stern, serious, tight-lipped… as if speaking sentenced him to years of hardship—and when it came to emotions, he was utterly clueless, only getting excited over a mech’s exhaust pipe. Ruan Yu: "I won’t join Auntie and Uncle in nagging you to marry anymore, because you might just be mech-sexual." Gu Xiuhan: "." I’m not. —— When Ruan Yu entered his mermaid maturity phase, his species’ innate telepathy kept evolving. At first, it was the murmurs of thoughts. Then, mental images. Then, 4K ultra HD Blu-ray mental images… With every upgrade to Ruan Yu’s telepathy, General Gu’s upright, noble, ice-cold, ascetic image crumbled further. Flushed red, Ruan Yu whispered to Gu Xiuhan in embarrassment: "What are you thinking about… can you *not* think about it? You’re being so weird…" Gu Xiuhan: "…Sorry." He tried to control his thoughts—only for them to spiral worse. #PinningYouAgainstTheWallKissingYouWithRedEyes# #SorryCanWePretendThatLastOneDidn’tHappen# #ItWasn’tMeThisBrainJustDoesn’tListen# --- **[Expect Cuteness & Tropes]** *Extremely soft (like, *eight-level* soft) botto—bimbo beauty + universal pampering + everyone loves him, even passing scallops and sea urchins adore him, LMAO. *Minor rival gongs appear but shou only falls for the main gong. *Pure romance fluff.
