Synopsis

At first glance, Emiri and Mia are twin sisters who seem to get along well. However, the younger sister looks down on her older sister. The kind-hearted older sister is unaware of this and dotes on her cute younger sister.

One day, Emiri finds out that her ordinary, plain, and shy older sister has a boyfriend, and is having sex with him. What's more, her partner is one of the most handsome guys in school...

While they look alike in appearance and face, Emiri's younger sister is superior on the inside and proactive in everything she does. Naturally, she thought she had gained more experience than her older sister... She was frustrated to find out that her older sister, who is so slow with men, has a boyfriend, and even had sex with him. But then, a brilliant idea poped into her head.

"That's it! I'll just take it!"

The younger sister realized that her older sister was the only one who always got the gifts, and that she often took them secretly. Naturally, she began to think that she should do the same this time...
