It's a breath of fresh air. People calling her a carnivore is rather delusional. She's just your airheaded weirdo. Just like Sakaki from Azumanga Daioh. Just take a look at both of her parents, and you'll understand why she is like that. The MC is your average guy, but not a total wimp. He considers other people's feelings pretty well, hence why he has two loyal, ikemen, weirdo childhood friends.
The characters in this story are quite colorful and not boring. Chihara's nest friend, the two weirdo ikemen, the parents, his sister, and even the faceless school teacher are really funny. And best of all, no overly horny loud male friend that just wants to get the girls troupe. Thank god those tropes are dead.
It's a full comedy with a slice of sweet romcom. I hope this will get an anime since both of the main characters are really sweet.
