Running around with the appearance of a boy, the lively commoner girl Tiese, had a beautiful and perfect childhood friend. He, since childhood, didn’t realize that Tiese was a girl, yet was so kind that he felt moral responsibility every time she ended up getting hurt.

I will have to review this again later when more comes out, since it’s still only the beginning, literally she hasn’t even men the demon king yet!


i feel that Hero is obsessed with MC and wants her, but she’s currently at the demon king castle and I really am rooting for the demon king rather than the hero again this is my assumption till further notice

I read this using google translate but it seems that there is no communication at all to straighten out the misunderstanding...

It is exactly as the title said,

the hero friend loved her since way back. She is dense, horribly so.

The hero punished people that spread rumors or trying to come between them, but never really explain anything to her. That is the meat of the drama in this one.


I wouldn't recommend this as cute or interesting, its pretty bland to me.

the blessing of the spirit was interesting though, no matter how cliche it was

It's a fun story you'll like it.

The interaction between Tiese and the demon king along with the prime minister is really funny.
