Silver to Pink

Ginji (65), who has devoted himself to work in a rural town in Nagano, rich in nature, retired on his birthday. Just the next day, when he and his wife had planned to spend their retirement years in peace, Ginji's wife suddenly passes away.
Three weeks later, his daughter, her husband and his adoptive father Momota (53), came to check on him and discover Ginji in a daze, with his room in disarray.
While Momota was efficiently cleaning up the house, Ginji ends up drowning in the bathtub, leaving him in a dangerous state. As Momota hesitates to administer artificial respiration, he regains consciousness.
Seeing Momota's face turning red at his nude sight, Ginji is surprised saying, "You're making a voice like a woman" but in fact Momota is gay...
Ginji (Silver), a stubborn old man from the Showa era who lost his wife and has zero housekeeping skills, and Momota (Pink), a devilish gay former middle school teacher with low self-esteem and a handicap, live under the same roof and grow closer as they are taught how to do housework, in this middle-aged elderly care home x BL!? x drama!
