I am looking for a manga or One-shot (I do not remember ) where Seme was so in love with uke, he decided to pretend to be someone else. He pretended to be a wealthy man with a car (it was the car of his boss). In some romantic scene he apologized uke, but uke did not know why. Later, uke discovers the truth, and he says he still loves Seme. (Uke was short and sweet, Seme tall and handsome)

Please, my dear friends, if you know the title of this story, let me know.

"The Wealthiness of Poverty" by Yamamoto Kotetsuko?

Yeah! This is it! Thank you so much, honey!
