The story of the office worker Kōji, who is in love with the university student Ichigo, his childhood friend. Despite that, he prefers to keep his feelings hidden, although suddenly something will happen that was not expected.

From cdJapan:
The youngest childhood friend of Kōji, Ichigo, who has been like a brother to him since he was a child, suddenly asks him a question that he can't believe his ears.
Koji, who has always loved and spoiled Ichigo, decides to protect him after he anxiously told him that he is gay, "I will protect him!”
He decides to confess his feelings to Ichigo when he graduates from high school...and watches over him. However, when another boy confesses his feelings for him at the graduation, he realizes that he has no pulse before he takes action.
He is puzzled by his request to check his moaning voice, but he accepts the request rather than leave it to another man. The two one-sided love starts to move with "panting"!
A strong-faced, caring businessman and an innocent, pampered, devilish college student are in a nurturing, doting love story with an age difference between them.
