Dazai and Guest met in the hospital courtyard. They got along perfectly and became close friends. Meeting in the courtyard every day eventually became their routine. Then one day, Guest suddenly died from the illness. However, Dazai continues to wait, unaware that Guest has passed away. Today, once again, he is beneath the cherry blossom tree in the courtyard. (Since the illness Dazai and Guest suffer from is misunderstood as an incurable contagious disease, they cannot leave the hospital.)
