Being friends with Eri is profitable. She’s beautiful, smart and has a strong will. In other words, she’s an opposite type of Hana. That’s why Hana wishes them to be together forever.
When Eri decides to pursue her dream of stage artist in the city, Hana’s dream fades away. Hana thinks she betrays her.
But, being separated physically is not the same with taking distance of each other’s heart. They just have to remember their vow: to be friends forever.
Personally, I always like friendship theme. But, this one is so flat. I can hardly pull my emotion of it.
