I don´t remember the manga's or the mangaka's name but I recall the story: it's about a straight guy who is a computer company owner who falls in love with his employee (a pretty blond young man). They work making interface screens and both work a lot of hours together, this is how the relationship happens.
I know it's not much information but that's all I have. Thanks in advance for those who could help.
