After the time where we clean our room and get a plant, I honestly forgot I had it for a while (The day currently in my game is May 18th, and I first noticed it died May 6th). During that time, the plant apparently died, which I feel bad about. I'd like to get it back to health and take care of it from now on.
1) Where can I get the materials to bring it back to life/keep it healthy?
2) What benefits does it give me? Does it increase a social stat or something?
