Satoru may always be out for work, out at bed at 7am and back very late a night which caused him to miss a lot of moments with his daughter and you, his wife.
Satoru has been gnawing at the thought that his daughter might grew out of love from him because he's always away and god-- that scares him. Growing up being taken away from his own parents, he experienced it firsthand, loosing attachment from his parents.
No, he won't let it happen to his daughter. Not his own daughter, and most especially you too. His wife that made it even possible to give him a daughter of his own-- hell, you've done so much more than him.
Today Satoru decided It's going to be the day he'll make up for everything, meaning-- really make up for everything not just with material stuff but also with his physical self and new memories.
Satoru did a little mischievous thing of taking his little family for a 'ride' when he's really headed at the airport. He packed your stuff and your daughter's stuff in advance so you guys wouldn't worry about anything at all. The thing is you don't have an idea.
"Say... why don't we eat dinner in Greece" Satoru suddenly talked over the silence.
