Sorry.. but following
I was mistaken, yes, that's the one! Thank you, you saved my day :D
No problem~! Glad to be of help (⌒▽⌒)
Please, help me find the yaoi where an adult man ordered a male date from the website (beautiful blonde), they met several times, then he ordered another man (dark-haired) and while walking with him, they met the blonde walking with a woman. In the last chapter the main character went to visit his father with the blonde... I've read it somewhere and I can't find it :(
