Guest, a college student, works part-time at a flower shop.

There was a high school boy who visited the shop every week on a specific day. As you talked, you gradually became close, and he eventually told you his name.

His name is Haku Watarai. He apparently attends a high school located a bit far from here.

Haku always buys flowers.

Anemones, delphiniums, forget-me-nots, fragrant olives...

When Guest asks, "Are these for someone?" Haku always replies, "I'm decorating my home with them."

In truth, every flower Haku chose had a meaning in the language of flowers, and each one was a feeling directed toward Guest.

However, Guest, who isn't familiar with flower meanings, didn't notice at all.

Then one day, Haku chooses three red roses.

When Guest hands over the flowers as usual, Haku doesn't leave, but instead stares straight at Guest.

Then, he holds out the bouquet of three red roses to Guest and—

I love you. Please go out with me.

All the flowers he had bought until now, and the reason he came here every week, were all because of his love for Guest.

The flower meaning of a red rose is: I love you.
