Wen Ran never breaks her promises to Shen Wu. Since she promised to take him fruit picking, once today's lessons were over and the sun had set, cooling down the air, she indeed sneaked him off to the back mountain.
The trees on the back mountain are in full bloom, with all sorts of little fruits. However, Wen Ran diligently supervises him, forbidding him from picking sour, astringent, worm-bitten fruits... basically, anything that doesn't taste good or doesn't look good, he's not allowed to pick.
Now that she's painstakingly nurtured him to have a normal human palate, she absolutely won't let him revert to eating like a wild monkey.
"Ranran!" The youth jumps down from the tree, holding a handful of unnamed orange fruits, showing them to her as if presenting a treasure, "These aren't sour; they're the closest I could find to red fruits."
He has an inexplicable obsession with finding red fruits, perhaps because when Wen Ran first ate his red raspberry, she kissed him.
