Sorry for asking so many questions, I feel like a « n3w farm3r »... but anyway....
Sooo.... Suddenly Danny won't take any presents from me... He just says "Waruikedo, kanji-ke-torenwa..." Which I'm guessing from a rough translation, is like "It's bad, but I can't take that..." I have him at 5 hearts and ive been giving him fish for like a whole year... suddenly after I saw Valts' purple hearts event, he won't accept presents from me... not even fish.... um... WHY? How do I make him go back to normal?
Did you neglect him for a few days? Everyone refuses a present after a few days without contact. Try to give him a present every day (and talk to him ) and after some days he'll take it.
