The first episode is so good, it's such a simple anime but with very deep feelings, and storyline, despite the art feeling like it's from an old anime from the 2000s. But the characters are all still very charming. The Doctor is such a loud mouth, you'd think he's a quack, lol! But the solutions he gave was so good and cuts deep. I actually love it, and Kuro seems like he will be a lovable character too, I can't wait to watch more.
