Ryousei and Shougo are two artists involved in a continuous and ambiguous sexual relationship. Shougo thought that claiming Ryousei as his own would alleviate the feelings of helplessness, regret and loneliness that are plaguing him. Ryousei, although captivated by Shuugo, began to realize that he was just being used.

An opportunity eventually arrives for both Shougo and Ryousei to display their paintings at Shougo's elder brother's art exhibition in Tokyo. Shougo, who has had a complex about his elder brother ever since childhood, thought that "I may be able to return to Tokyo if this goes well", which gradually increased the pressure to succeed. Beneath the starry sky, a paint brush paints a story of youthful love.
