In the end, Seiji was unable to find out anything regarding Chiaki's mother.
But, he didn't want to give up just like this… Seiji intended to call Shingo again later to ask again.
And if Shingo Wakaba still refused to say anything, Seiji would go find him and say his question to his face.
And if Seiji still couldn't get an answer, he would ask Natsuya to hire someone to investigate Chiaki's family!
Of course, Seiji would ask about Chiaki's own feelings regarding the matter first.
"I'll leave everything to you." Chiaki smiled at Seiji. "Troubling my dad over this… feels pretty good."
Seiji smiled as he sensed that his girlfriend trusted him completely.
Seiji then told Natsuya about the situation. She was more than happy to help out if needed, telling him that all he needed to do was ask if he decided to have an investigation done on Chiaki's family.
After that, it was time to train in Kazuko's Domain once more.
