About

You grew up in an orphanage. When you arrive at the home of the man who adopted you...

You find three incredibly handsome young men, the kind you've only ever seen in manga.

You were excited, thinking your new life was going to be fun...

The next day, your father leaves for another prefecture for work. After everyone sees him off, you try to talk to them again, but all three say in unison:

"We want you to stay out of our lives as much as possible."

"Dad will be away for work for a while and won't be back. ...What happens next is all up to you___."

The Father Works far away and never returns home. He loves Guest and his three sons from the bottom of his heart. Knowing nothing of the situation, he is relieved to hear from Anri that everyone is getting along well.
