I'm the Cute and Cunning Winner

Synopsis

"I am a cutie, and I know it, because all the men are crazy about cute little ol' me. It's the same no matter where I go. It's just common knowledge at this point." This was Kotone. She was a cute young lady who led a life of unparalleled popularity. But then Nazuna, a more seasoned cutie, would appear in front of her. No matter what, when, or why, Kotone is overlooked by Nazuna's cute charm, which has Kotone in a panic. Oh, and then there's the handsome senior at work...! "Why!", Kotone wonders. This has never happened to her before! Truth be told, Nazuna is also uneasy about Kotone who she will not underestimate in this battle of the cuties. (Source: Manga Plaza)
