Cute and simple. Of course, the relationship is not appropriate as it's a teacher and student. But enjoy it. The feeling are pure and the relationship is not toxic. They communicate and that's a key in relationship.
I really want to give this manga more of a 4.5, but I loved the characters though the teacher/student trope is cliché. Their changes and realizations about their feelings felt realistic, even though the story overall is kinda fast-paced. I also kind of wanted a little more drama, but if you want a uke with a slightly tragic backstory and a relentless adorable seme, look no further!
