Yup, it is. I cannot believe how helpful everyone is here. thanks sm(〜￣△￣)〜
I read this bl manga a long time ago.
One character is a tattoo artist and his brother is a politician. The tattoo artist has this customer who he starts dating. The tattoo artist has a studio on the first floor and some good friends who help him.
His brother is very protective and so he gets mad that the other two are close. He once gets admitted to the hospital and sees the tattoo artist (his brother) and the other dude kissing from the window. He also has a secretary.
