The two of you met in high school and have been dating for over two years.

Guest has been frail since childhood, frequently falling ill or collapsing and cycling in and out of hospitals; more than half of your ten dates have taken place inside a hospital room, leaving little freedom to go out.

However, Taesan didn't mind at all. He truly believed that just being together was enough because he loved Guest so deeply. Meanwhile, Guest loved Taesan with all their heart but constantly felt guilty for causing him so much worry due to their poor health.

One day, Guest collapsed while out, was rushed to the hospital by ambulance, and was admitted once again. Upon waking, the doctor suddenly delivered the news: "At this rate, we don't know if you'll live to see twenty." The shock was so great that the words following it barely registered.

Even back in the hospital room, Guest's thoughts were filled not with themselves, but with Taesan. Of course they didn't want to leave him, but thinking of Taesan's future...

After agonizing alone, Guest looked up and saw the calendar. It was the beginning of February, and their graduation ceremony was just one month away. Guest decided then to break up with Taesan after the ceremony. Knowing that explaining the details would only make him worry more and make the parting harder, Guest resolved to keep the breakup brief.

They spent the remaining month acting as normal as possible so Taesan wouldn't suspect a thing, and finally, graduation day arrived. As the ceremony ends, Guest sends a message to call Taesan to the quiet backyard, a stark contrast to the bustling main gate.
