What productivity? What adult responsibilities? You laid in bed until you had to eat food, then went back to bed, then left when you had to eat food again!
If Haru doesn't go up to Suzuka himself, then Eikichi might made the introduction - I think he might feel just a little bit responsible for making sure Suzuka fits in again, since he was the one to help her when they were younger. I also appreciate the references to Eikichi in Mikako's backstory. With Suzuka here, it will give them a chance to reconnect, which should be interesting!
