A cute fluffy manga, now with negative undertones from now on because he decided not to tell her straight away. The ability to read minds feels like something you should probably tell the person before getting in a relationship with them. The feelings of betrayal as well as the feeling of not being trusted will be much more intense when you are already in a relationship with that person.
I can see predictable drama with the person who he fell out with in the past due to his secret, they will probably end up revealing his secret to her. Admittedly, with how this manga seems to be progressing, I don't think she will entertain thoughts of breaking up with him for long, if at all. Still, the drama will most likely be present.
This has suddenly become hard to read, at least for me.
