149 If that's not an obsession, I don't know what is

Rie is feeling strange in her own house. Kiyohira and Yuta have their backs to her. The father and son are making food in the kitchen. Yuta is standing on the stool, helping Kiyohira. They speak in the low voices, making here jealous of their relationship.

When did they get so close? Yuta stayed 5 years with her including the time in her womb. He met Kiyohira for less than 2 days. How come 2 days are more effective than 5 years? He didn't help her during cooking before. Is she supposed to wait here? 

Meanwhile, Yuta is helping his father because he's curious about how his father makes the pancakes so delicious. 

Bored, she finds her phone. Tsuchiya San hasn't contacted her. There are a few messages from her reporting Yuta's and Kiyohira's activities.
