I think it's necessary to have the rape tag because even if it was a misunderstanding, it can trigger a lot of people because half of the manga we thought that.
I was expecting but at the same time wasn't expecting everything that happen, I really like it but I feel everyone had selfish reasons of why the misunderstanding, both of them thought of what it was better for them and I can't help but feel uncomfortable. But we held a good character development and a good relationship development.
