It's not easy being beautiful. The envy, the jealousy, the vicious rumors spread by your best friend. That's life for young Momo. While everyone thinks that Momo is a wild party girl, the reality is that she is shy and lonely. Can Momo confess her love to her classmate, Toji, or will her best friend Sae steal him away? It's a bittersweet drama of growing up and fitting in that will charm readers everywhere.

The story is about an ordinary (and rather unpopular) girl named Ageha who is constantly overshadowed by her popular and beautiful twin sister, Hana. Because Ageha grew up in the countryside with their grandmother while Hana was raised by their parents, the two girls ended up with drastically different personalities.

For the most part, Ageha remains a silent and hidden student in the school, with only one friend (who isn't all that nice either). In fact, nobody even really knows that she is Hana's twin sister, because despite looking alike, there is still a large gap between the levels of their beauty and popularity. When Hana finds out that Ageha has a crush on a cute boy named Ryuusei (who is actually Ageha's childhood friend from the countryside), Hana becomes curious about their relationship.

However, after hearing that Ryuusei hates people like Hana, Hana becomes irritated and using her charming personality, actually manages to snag Ryuusei as her boyfriend! Ageha is left with no one, but thanks to the strange (and attractive) new school counselor, and some unexpected allies, Ageha decides to do her best and take Ryuusei back.

Momo and Kairi are at the peak of their relationship, but still not married?! The pressure is on! Sae can’t stand to see this couple happy, and she won’t stand for it! Touji also seems to already have a shadow hanging in his past after becoming an adult … What happened? Get ready for this love train to move full-steam ahead once again!
