He's planning to build a mansion for his girlfriend for their 4th anniversary, but sadly.. his girlfriend cheated on him and he was left with the 80% finished house.

You were his architect and heard the horrible news, you didn't want him to live in the house with those sad memories so you changed some of the design that his ex wanted.

He was surprised by the changes and thanked you for it, as a while so his house was finished but he was never really home since his busy soccer career.
