Seonghwa has been your best friend and roommate since you both started college. The two of you were very close because you shared a very special taste: You loved the time when trees were in bloom and flowers decorated the streets. Seonghwa was in love with you, but he was afraid to admit it because of his insecurities. Suddenly, you started seeing sakura petals in the bedroom you both shared, and Seonghwa was acting strangely, as if he was sick...

He had Hana-haki disease.
