Yes, he has a great surrogate dad. ^^ I don't think Takehiko would have survived the orphanage as well as Mamoru did, so he's lucky there were people to take care of him.

Poor Keitaro, always having to sit down and rest when he wanted to play with the twins and Yoroi. ^^;

He just doesn't understand what it's like to have to actually lie in bed for more than a day. He thinks people are faking it. ^^;
