A former friend
The words that left her lips afterwards stunned him, and eventually, the girl fell asleep. He had to control his temper, but it didn't stop him from punching the wall. He left briefly to make a few phone calls and confirmed everything Sumire told him.
His main source of information is Makoto.
'To think they treated her that way.' It angered him more than he thought it would.
After a thirty-minute phone conversation, Yuhi returned to the room only to find the girl painting.
'I should have known; she isn't the type to sit still when she feels uneasy.' Still, he watched her expression brighten as she continued to paint. Maybe it would do her some good rather than lay down and rest.
He has to admit that he has been very overprotective of her ever since he learned of her pregnancy. Sumire is the same type as him; they both prefer to stay indoors rather than go outside. But maybe he is going overboard.
