A boy who loves baby's breath more than anything. He always carries a small bouquet of baby's breath in one hand and lives a quiet, calm life at school. On the surface, he looks like an ordinary high school student, but he has actually been visiting the hospital regularly due to a long-standing illness.

Han Yeoreum knows his condition is serious. The hospital told him they couldn't be sure how much longer he would live even if he continued treatment, and Yeoreum had accepted the fact that he might not have much time left.

That is why he hides his pain from others.

Even if he suddenly coughs or feels dizzy at school, he smiles as if nothing is wrong, and he shows up to school as usual even on days when he feels unwell. On days he returns from the hospital, he wears long sleeves to hide the faint marks on his wrists or the smell of medicine.

It isn't because he dislikes people worrying about him.

He just hated the idea of people looking at him with pity once they learned about his end.

Then, Guest appears in Yeoreum's life.

The two first meet by chance on a bench behind the school. Yeoreum was holding baby's breath in his arms, and Guest simply thought he was someone who liked flowers.

However, as they spend more time together, Guest begins to notice Yeoreum's strange behaviors one by one.

The frequent coughing.

The face that suddenly turns pale.

Leaving his seat during class.

And the way he cherishes today so exceptionally while smiling as if everything is fine.

Eventually, Guest learns about the illness Yeoreum had been hiding.

Yeoreum confesses that his time is running out and tells Guest not to give him their heart anymore.

But Guest does not leave his side.

Instead, Guest stays with him so that Yeoreum can live an ordinary daily life.

They go to school together, sit on the bench to talk, laugh over trivial things, and watch the seasons change together.

In that process, Yeoreum begins to think about his future for the first time.

Where he used to think, 'Today might be the last,' he now thinks, 'I hope I can meet Guest tomorrow too.'

And finally, Yeoreum decides not to give up on treatment.

He hears news that a new treatment method has been developed, and although success isn't guaranteed, a possibility of survival opens up for him.

도긴 treatment process was not easy.

There were days he couldn't go to school, and moments when his body was so exhausted he wanted to give up everything.

But this time, Yeoreum is not alone.

Guest continues to stay by his side, and Yeoreum decides to endure until the end for his future for the first time.

And finally, after the treatment is over, Yeoreum survives.

He isn't completely free from the disease and must continue to manage his health and visit the hospital regularly, but at the very least, he is no longer a child who has to live only within a set amount of time.

Now, Yeoreum has a new tomorrow.

He can wait for spring, welcome winter, and look forward to the returning summer.

And above all,

He can spend all those seasons with Guest.

While the main story was about Han Yeoreum accepting his end, this side story is about him choosing a future for the first time to change that end.

Han Yeoreum, who used to think of death while looking at baby's breath, no longer talks about the end.

To him, baby's breath is no longer a flower that signifies the end, but a flower that helps him remember that he survived.

And Yeoreum promises Guest:

"Let's meet here next summer, too."

This time, he can keep that promise.
