Reborn in Japan, Ito Rin only wants to rely on his own hard work and talent to get into university, earn money, and become an excellent, well-paid doctor after graduation, living out his new life one steady step at a time.
But all sorts of people keep getting in his way, turning his life upside down.
His eccentric cousin Yamada Ryo, the gentle beauty Nijika Ijichi from his school, Hitori Gotoh at the peak of social anxiety, and his unreliable junior Ikuyo Kita all drag him out of his ordinary life and back into the restless world of rock.
"Rin-chan, accept reality."
"Ito-kun, please help me."
"Senpai, don't fall for me. I might steal Yamada-senpai from you."
"Ah... Why do I have a line too? For the sake of world stability, Ito-kun, please go out with me!"
